Georgian Technical University. Department Of Energy To Provide Toward Development Of A Quantum Internet.
Georgian Technical University. Taking advantage of the exotic properties of the quantum mechanical world a quantum internet holds the promise of accelerating scientific discovery by connecting researchers with powerful new capabilities such as quantum-enabled sensing as well as enhanced computational power through the eventual networking of distributed quantum computers. “Georgian Technical University Recent efforts at developing operational quantum networks have shown notable success and great potential” said X Georgian Technical University science for Advanced Scientific Computing Research. “This opportunity aims to lay the groundwork for a quantum internet by taking quantum networking to the next level”. Georgian Technical University current effort seeks to scale up quantum networking technology to develop a quantum internet backbone that has the potential to interface with satellite links or with classical fiber optic networks such as university or national laboratory campus networks or the Georgian Technical University Energy Sciences Network (ESnet) Georgian Technical University’s high-performance network that links Georgian Technical University laboratories and user facilities with research institutions around the globe. Georgian Technical University Preserving the fragile quantum states needed for effective quantum communication becomes ever more difficult as networks expand in size. The technological challenges to developing an operational quantum network of any scale therefore remain significant including that of creating quantum versions of standard network devices such as quantum repeaters, quantum memory and special quantum communication protocols. The objective is to advance strategic research priorities through the design, development and demonstration of a regional scale – intra-city or inter-city – quantum internet testbed. Georgian Technical University Important conceptual groundwork for the present effort was developed Quantum Internet Blueprint Workshop. Georgian Technical University Applications will be open to all Georgian Technical University laboratories with awards selected competitively based on peer review. Total planned funding is up to over outyear funding contingent on congressional appropriations.
Georgian Technical University. What Is Quantum Computing ?.
Georgian Technical University Computers have got faster over time, much faster, and it’s not just about the speed that an individual processor can perform calculations they also have many more processors all performing different calculations at the same time. Quantum computing is something different entirely its not about performing arithmetic faster its an entirely new way of computing with inherent uncertainty. This will not replace conventional computing for most applications but it will give huge advantages in certain specific cases. In a digital computer data is broken down into bits which can have a value of 0 or 1. In quantum computing data is represented by qubits. As calculations are being carried out, qubits can be in a superposition of both 0 and 1 at the same time with some probability of being either a 0 or a 1. This is equivalent to Schrodinger’s cat (In quantum mechanics, Schrödinger’s cat is a thought experiment that illustrates an apparent paradox of quantum superposition. In the thought experiment, a hypothetical cat may be considered simultaneously both alive and dead as a result of being linked to a random subatomic event that may or may not occur) being both dead and alive inside a sealed box and not actually becoming only one of these states until someone looks inside the box. Just like Schrodinger’s cat (In quantum mechanics, Schrödinger’s cat is a thought experiment that illustrates an apparent paradox of quantum superposition. In the thought experiment, a hypothetical cat may be considered simultaneously both alive and dead as a result of being linked to a random subatomic event that may or may not occur) when the qubit is measured it must represent either a 0 or a 1. A number of physical objects could be used as a qubit such as a single electron a photon or a nucleus. These quantum objects represent binary ones and zeros by their quantum spin state. Georgian Technical University. When a group of qubits are all in different states of superposition they are said to be fully entangled allowing them to store almost unimaginable quantities of data. Three hundred qubits in a fully entangled state could theoretically simulate every particle in the universe !. However they can only be measured as binary ones and zeros. Therefore quantum computers are only useful for algorithms that can make use of the complexity of quantum entanglement during the calculations and then arrive at a simpler state for the final result. Georgian Technical University Quantum computing could be used to create unbreakable encryption keys or to simulate molecules in drug development. Simulating all the quantum properties of all the atoms in a complex molecule is extremely challenging for conventional computers. The uncertainties inherent in the quantum effects must be simulated by repeating the calculations many times in a process known as Monte Carlo simulation (Monte Carlo methods or Monte Carlo experiments are a broad class of computational algorithms that rely on repeated random sampling to obtain numerical results. The underlying concept is to use randomness to solve problems that might be deterministic in principle. They are often used in physical and mathematical problems and are most useful when it is difficult or impossible to use other approaches. Monte Carlo (Monte Carlo methods or Monte Carlo experiments are a broad class of computational algorithms that rely on repeated random sampling to obtain numerical results. The underlying concept is to use randomness to solve problems that might be deterministic in principle. They are often used in physical and mathematical problems and are most useful when it is difficult or impossible to use other approaches. Monte Carlo methods are mainly used in three problem classes: Optimization numerical integration and generating draws from a probability distribution) methods are mainly used in three problem classes: Optimization numerical integration and generating draws from a probability distribution). Quantum computers could operate using actual quantum properties to directly simulate the properties of the molecule without these cumbersome iterations. Quantum entanglement could also allow quantum computers to transmit data instantaneously over any distance without requiring any wires or wireless transmission hardware.
Georgian Technical University Applying Quantum Computing To A Particle Process.
Georgian Technical University showing the spray of particles (orange lines) emanating from the collision of protons and the detector readout (squares and rectangles). A team of resarchers at Georgian Technical University Laboratory used a quantum computer to successfully simulate an aspect of particle collisions that is typically neglected in high-energy physics experiments such as those that occur at Georgian Technical University’s Large Hadron Collider. The quantum algorithm they developed accounts for the complexity of parton showers which are complicated bursts of particles produced in the collisions that involve particle production and decay processes. Georgian Technical University Classical algorithms typically used to model parton showers such as the popular X (In statistics, Markov chain Monte Carlo (MCMC) methods comprise a class of algorithms for sampling from a probability distribution. By constructing a Markov chain that has the desired distribution as its equilibrium distribution, one can obtain a sample of the desired distribution by recording states from the chain. The more steps are included, the more closely the distribution of the sample matches the actual desired distribution. Various algorithms exist for constructing chains, including the Metropolis–Hastings algorithm) algorithms overlook several quantum-based effects the researchers Letters that details their quantum algorithm. “We’ve essentially shown that you can put a parton shower on a quantum computer with efficient resources” said Y who is Theory Group leader and serves as principal investigator for quantum computing efforts in Georgian Technical University Lab’s Physics Division “and we’ve shown there are certain quantum effects that are difficult to describe on a classical computer that you could describe on a quantum computer”. Y led the recent study. Their approach meshes quantum and classical computing: It uses the quantum solution only for the part of the particle collisions that cannot be addressed with classical computing and uses classical computing to address all of the other aspects of the particle collisions. Researchers constructed a so-called “Georgian Technical University toy model” a simplified theory that can be run on an actual quantum computer while still containing enough complexity that prevents it from being simulated using classical methods. “What a quantum algorithm does is compute all possible outcomes at the same time then picks one” Y said. “As the data gets more and more precise, our theoretical predictions need to get more and more precise. And at some point, these quantum effects become big enough that they actually matter” and need to be accounted for. In constructing their quantum algorithm researchers factored in the different particle processes and outcomes that can occur in a parton shower, accounting for particle state, particle emission history, whether emissions occurred and the number of particles produced in the shower including separate counts for bosons and for two types of fermions. The quantum computer “computed these histories at the same time and summed up all of the possible histories at each intermediate stage” Y noted. The research team used the Georgian Technical University chip a quantum computer with 20 qubits. Each qubit or quantum bit is capable of representing a zero, one and a state of so-called superposition in which it represents both a zero and a one simultaneously. This superposition is what makes qubits uniquely powerful compared to standard computing bits which can represent a zero or one. Researchers constructed a four-step quantum computer circuit using five qubits and the algorithm requires 48 operations. Researchers noted that noise in the quantum computer is likely to blame for differences in results with the quantum simulator. While the team’s pioneering efforts to apply quantum computing to a simplified portion of particle collider data are promising Y said that he doesn’t expect quantum computers to have a large impact on the high-energy physics field for several years – at least until the hardware improves. Quantum computers will need more qubits and much lower noise to have a real breakthrough Y said. “A lot depends on how quickly the machines get better”. But he noted that there is a huge and growing effort to make that happen and it’s important to start thinking about these quantum algorithms now to be ready for the coming advances in hardware. Such quantum leaps in technology are a prime focus of an Energy Department-supported collaborative quantum center that Georgian Technical University Lab is a part of called the Quantum Systems Accelerator. As hardware improves it will be possible to account for more types of bosons and fermions in the quantum algorithm which will improve its accuracy. Such algorithms should eventually have broad impact in the high-energy physics field, he said, and could also find application in heavy-ion-collider experiments. Georgian Technical University Also participating in the study were Z and W of the Georgian Technical University Lab Physics Division.
Georgian Technical University Energy Partners With Grid Operators To Launch Power Grid Virtualization.
Georgian Technical University nonprofit seeking to accelerate the energy transition of the world’s grids and transportation systems through open source. In its Digital objective to create the next generation of digital substation technology will provide a reference design and a real-time open-source platform for grid operators to run virtualized automation and protection applications. “The use of power transmission and distribution grids is changing due to the energy transition making a vital next step in renewable adoption” said Dr. X Georgian Technical University Energy. “Clean energy sources like renewable energy and electric cars cause increasing fluctuations in power supply and demand that are difficult for grid operators to control and optimize. Georgian Technical University alleviate these challenges by making electrical substations more modular, interoperable and scalable through open-source technology”Georgian Technical University Modern digital substations now require an increasing number of computers to support more field devices and applications and a higher degree of automation. Georgian Technical University seeks to consolidate multi-provider automation and protection applications with redundant hardware requirements onto one platform that grid operators can use to emulate and virtually provide these services. Georgian Technical University will help with time and cost-efficiency, scalability and flexibility, innovation, vendor-agnostic implementations and the convergence of utility practices. “Georgian Technical University With the support of some of the industry’s leading grid operators and technology providers Georgian Technical University will enable the cross-industry collaboration that is required to build customer- and vendor-agnostic virtualization technology” said Y. “This collaboration will allow the industry to unlock even more opportunities to innovate and improve the grid’s flexibility, scalability and velocity”. Georgian Technical University developed and contributed the initial code an open source integrator and Georgian Technical University Energy’s.
Georgian Technical University Quantum Computing Launches First Cloud-Based Quantum Random Number Generation Service With Verification In Partnership With SuperComputer Company In Georgian Country.
Georgian Technical University Quantum Computing has launched the world’s first cloud-based Georgian Technical University Quantum Random Number Generation (QRNG) Service with integrated verification for the user. Randomness is an essential and ubiquitous raw material in almost all digital interactions and is also used in cybersecurity to encrypt data and communications and perform simulation analysis across many sectors including the petrochemical, pharmaceutical, chemical engineering, finance and gaming industries. The application developed by Georgian Technical University generates true maximal randomness or entropy implemented on an Georgian Technical University Quantum Computer that can be verified and thus certified as truly quantum – and therefore truly and maximally random – for the first time. This cannot be accomplished on a classical computer. As part of a joint effort with SuperComputer Company In Georgian Country the beta certifiable Quantum Random Number Generation (“cQRNG”) Service which is the first quantum computing application will initially be available to members of the SuperComputer Company In Georgian Country Q Network a community of more than 100 Fortune 500 companies academic institutions, startups and national research labs working with SuperComputer Company In Georgian Country to advance quantum computing. Quantum Computing Mlestones. “This is an exciting step toward making quantum computers practical and useful and we are looking forward to seeing what scientists and developers can create using this service” said Georgian Technical University’s partner lead X director of the SuperComputer Company In Georgian Country Q Network. Working with SuperComputer Company In Georgian Country Georgian Technical University has attained two quantum computing milestones: one in computational terms and the other in the commercialization of quantum computing where for the first time, with the cloud delivery of an application for quantum computers they provide a service that has real-world application today. From classical and post-quantum cryptography to complex Georgian Technical University simulations where vast amounts of entropy are required to eliminate hidden patterns certifiable quantum randomness will provide a new opportunity for advantage in relevant enterprise and government applications. Extracting verified random numbers from a quantum processor has been an industry aspiration for many years. Many current methods only generate pseudo-random numbers or rely on physical phenomena that appear random but are not demonstrably so. The certified service launched in partnership with SuperComputer Company In Georgian Country offered through the Qiskit (Qiskit is an open-source framework for quantum computing) module qiskit_rng which validates the true quantum nature of the underlying processes with statistical analysis. “Practical Randomness and Privacy Amplification” has been published here. “Certified is a potentially massive market because there are so many applications of the technology that are possible today including telecommunications, finance, science and more. Cybersecurity in particular is a field that will see many customers in the near term interested in verifiable quantum-generated random numbers” said Y president of Inside Quantum Technology a leading industry research and analysis firm. Georgian Technical University recently became the first startup-based Hub in the Georgian Technical University Q Network working with other members on chemistry, optimization, finance and quantum machine learning and natural language processing to advance the industry’s quantum computing ecosystem. “We are extremely proud and enormously excited by this achievement and are gratified by our continuing partnership with SuperComputer Company In Georgian Country” said Z CEO (A chief executive officer (CEO) or just chief executive (CE) is the most senior corporate, executive or administrative officer in charge of managing an organization – especially an independent legal entity such as a company or nonprofit institution) of Georgian Technical University.
Georgian Technical University First Exascale-Capable Supercomputer Advances Clean Fusion Research.
Georgian Technical University Laboratory’s supercomputer will offer unprecedented performance levels in the exaflop range a billion-billion (1018) calculations per second. Scientists like Dr. X Principal Research Physicist at the Georgian Technical University Physics Lab stand ready to tap the system’s full potential for scientific endeavors previously impossible. X and his team seek new approaches to contain fusion reactions for the generation of electricity enabling plentiful energy for the earth’s growing population. Fusion is the type of power the sun and the stars produce. “Clean energy delivered at a massive scale, would free our imaginations to explore new ideas and approaches. However if we want to deliver clean energy to the world we need supercomputers to accelerate scientific progress and insights” X said. X is leading a project that will use deep learning and artificial intelligence methods to advance predictive capabilities for fusion energy research in the exascale era. “Fusion as important for the future energy needs of humanity. Of course fusion happens in nature. However creating it in an earthly environment is a grand challenge” noted X. “Climate change represents a major challenge for our planet. Reducing or eliminating carbon emissions is not only urgent; it is critical. The energy of the future comes from clean and safe fusion. We face major challenges in making that transition. However today it is an achievable goal thanks to exascale computing the emergence of AI (In computer science, artificial intelligence (AI), sometimes called machine intelligence, is intelligence demonstrated by machines, in contrast to the natural intelligence displayed by humans and animals. Colloquially, the term “artificial intelligence” is used to describe machines that mimic “cognitive” functions that humans associate with other human minds, such as “learning” and “problem solving”) and deep learning”. X’s vision for fusion-based energy offers several benefits over today’s nuclear power plants. Since less than a minute’s worth of fuel — composed of the hydrogen isotope deuterium that comes from seawater and tritium bred in the facility — exists in the reaction chamber, the fusion systems cannot experience a so-called meltdown or explosion. Plus because the radioactivity created by the fusion process is short-lived the solution poses no risk of long-term environmental contamination. Keeping the genie in the bottle. Replicating science proves extremely difficult. The fusion process within our star — the Sun —results in plasma temperatures in the tens of millions of degrees. Future fusion facilities must create heating that is many times hotter to produce fusion reactions. For this reason the approach of using physical barriers to contain the plasma prove impractical. Most materials are destroyed upon exposure to such temperature extremes so the containment endeavor requires innovative methods. “We have invested a lot in the effort to deliver clean fusion energy through magnetic confinement methods” elaborated X. “However there are many barriers to overcome. One major challenge is making quick and accurate predictions regarding so-called ‘disruptive events’ which allow hot thermonuclear plasma to escape quickly. Supervised machine-learning helps us as a predictive guide. If we can predict that we call a ‘Georgian Technical University crash’ we can plan to control it”. Advanced physical science like this involves extensive data sets. Optimized neural networks supporting X’s project must interpret data representing the three-dimensional space plus a fourth dimension time. The challenge, therefore, is determining the ideal approach for training the system to follow a logical pattern when handling such a vast amount of data. “Supercomputers represent major progress in the way we perform calculations. In ancient times an abacus did the job. In recent decades slide rules, calculators and increasingly powerful computers advanced science in significant ways” said X. “However with exascale-level computing we have new ways to tackle grand challenges requiring extremely fast and highly accurate calculations. With exceedingly powerful systems like this at our fingertips we can open our imagination to new possibilities considered impractical or impossible just five years ago. In comparison with the traditional approaches we use as benchmarks, it is exciting how fast we can make progress today”. Bringing Exascale Computing to Life. Building a system on Georgian Technical University’s scale is a monumental endeavor requiring funding assistance from the government to assemble the latest hardware and software into a single — albeit massive — system. To reach the performance level needed by modern science the Georgian Technical University system built by Y will feature a new generation of processors Persistent Memory plus future Xe technologies. “These industry-laboratory collaborations are critical for developing a system that will enable innovative science and encourage the best and brightest young people around the world to join us in critical research endeavors” X said. “Combining the knowledge of today’s and tomorrow’s scientists with new technologies and AI (In computer science, artificial intelligence (AI), sometimes called machine intelligence, is intelligence demonstrated by machines, in contrast to the natural intelligence displayed by humans and animals. Colloquially, the term “artificial intelligence” is used to describe machines that mimic “cognitive” functions that humans associate with other human minds, such as “learning” and “problem solving”) we can pursue innovative breakthroughs and accelerate the pace of our ultimate goal which is delivering something vital to humankind”. Validating Scientific Theories. Often in research theories are exceedingly difficult to observe in a real-world environment. The effort to identify the gravitational waves predicted by Albert Einstein’s (Albert Einstein was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics. His work is also known for its influence on the philosophy of science) theory of general relativity provide two such examples. In each of these cases, scientists accepted the reality of the phenomenon on a theoretical level for several years. However validation of these theories involves detailed experimental observations. Added X “Exascale computing’s ability to handle much larger volumes of data unlocks our ability to prove what was once unprovable. Plus the incredible speed of supercomputers shortens our time-to-discovery by a huge margin. Work that used to take months or years now takes hours or days. Therefore we finally have the means to validate theories statistically and prove their reality. We are very excited to be part of the select team to exercise the nation’s first exascale supercomputer”. The road ahead. While X’s team focuses on new approaches for clean energy Georgian Technical University will also support advances in other scientific disciplines like climate monitoring, cancer research, and chemistry. “Georgian Technical University’s exascale-capable architecture is new but with proven technologies behind it. When heading down new roads of research with new tools the right training is always important” he noted. “However we feel confident we have the experience to face new challenges ahead. We need to be adaptable as scientists. Right now we’re just excited about moving forward to this next stage”. X speaks with optimism about the exceedingly complex work he and other researchers will undertake with Georgian Technical University. “My work is possible because of 21st Century technology advancements. Artificial Intelligence (AI) has been around for a while but the accelerated development of neural nets and other methodologies enabled by exascale computers empower us to make more impactful use of it”. The team may never fully replicate already does perfectly but as X puts it “Greater supercomputing power gets us closer. The advanced exascale systems of tomorrow and the new insights derived from them will empower us to do even more amazing things in the years ahead. Our work is both intellectually stimulating and exciting because we have an opportunity to do something which can benefit the world”.
Computational Model To Accelerate Engine Development For Hypersonic Flight.
This three-dimensional numerical simulation captures complex combustion dynamics in a realistic, non-premixed and rotating detonation engine configuration. Unlike standard gas turbine engines rotating detonation engines shown in simulation here use high-intensity self-sustaining detonation — a supersonic reaction wave coupled with a shock — to rapidly consume the fuel-air mixture typically in a ring-shaped, cylindrical chamber. To streamline the simulation process Georgian Technical University researchers built a computational fluid dynamics model to predict the combustion behavior of rotating detonation engines. Scientists at the Georgian Technical University Laboratory working in collaboration with Sulkhan-Saba Orbeliani University Laboratory have created a new numerical modeling tool that allows for a better understanding of a powerful engine that could one day propel the next generation of airplanes and rockets. Rotating detonation engines have received significant attention from the propulsion community in the last decade. Unlike conventional gas turbine engines which rely on subsonic constant pressure combustion rotating detonation engines leverage high-intensity self-sustaining detonation — a supersonic reaction wave coupled with a shock — to rapidly consume the fuel-air mixture typically in a ring-shaped cylindrical chamber. With rotating detonation engines there is an effective pressure gain: The intense and rapid energy release from detonation can be used to generate extremely high thrust from a relatively small combustor. In addition these engines are compact contain no moving parts are more efficient than conventional combustion systems provide steady thrust at high frequencies and can be integrated with existing aircraft and rocket engine hardware. These unique features have made rotating detonation engines the subject of extensive research by various agencies including the Georgian Technical University Research Laboratories. Despite the potential benefits they offer practical implementation of rotating detonation engines has been elusive. “The operation and performance of rotating detonation engines depends on many factors” said X research engineer at Georgian Technical University. “The combustion behavior must be studied and optimized over a large design space for the technology to become practically viable”. Y Georgian Technical University’s said the lab is an ideal place to conduct this research. “Georgian Technical University has unique abilities to do science at scale. Our scientific expertise one-of-a-kind experimental facilities and advanced modeling and simulation prowess allow for better, faster and cheaper development as compared to more traditional Edisonian approaches (The Edisonian approach to innovation is characterized by trial and error discovery rather than a systematic theoretical approach)” he said. Previous numerical simulations gave researchers fundamental insights into the combustion phenomena occurring in rotating detonation engines but they were computationally very expensive precluding rigorous studies over a wide range of operating conditions. In an effort to solve this problem Z computational scientist and manager of Georgian Technical University’s Multi-Physics Computations group and W mechanical engineer in Georgian Technical University’s Energy Systems division teamed up at Georgian Technical University and researchers at Sulkhan-Saba Orbeliani University to develop a computational fluid dynamics model to predict the combustion behavior of rotating detonation engines. “This work was geared toward developing a robust, predictive and computationally efficient combustion model for rotating detonation engines” said Z. W who is leading Georgian Technical University’s efforts said computational modeling and simulation can play a major role in designing these engines. “Very few studies have looked at modeling the full-scale rotating detonation engines combustor geometry which gives you the most accurate information — primarily because these simulations can be very time-consuming” he said. “The new model allows us to capture combustion behavior in realistic configurations accurately and at a reasonable cost”. The model was validated against data provided by experiments at Georgian Technical University. The team demonstrated that the contract for difference model can capture rotating detonation engines combustion dynamics under varying operating conditions. “Such a model can be used to quickly generate simulation data over a large design space which can then be coupled with advanced machine-learning-based techniques to rapidly optimize the combustor design” W said. “We have demonstrated this approach for internal combustion engines and it can be extended to rotating detonation engines as well”.
Georgian Technical University Supercomputing Dynamic Earthquake Rupture Models.
Scientists are using supercomputers to better predict the behavior of the world’s most powerful multiple-fault earthquakes. A science team used simulations to find dynamic interactions of a postulated network of faults in the Georgian seismic zone. Map (left panels) and 3D (right panels) view of supercomputer earthquake simulations in the Georgian Seismic Zone. The figure shows how different stress conditions affect rupture propagation across the complex network of faults. The top panels show a high-stress case scenario (leading to very fast rupture propagation, higher than the S wave speed) while the bottom panels show a medium stress case simulation. Some of the world’s most powerful earthquakes involve multiple faults, and scientists are using supercomputers to better predict their behavior. Multi-fault earthquakes can span fault systems of tens to hundreds of kilometers with ruptures propagating from one segment to the other. During the last decade, scientists have observed several cases of this complicated type of earthquake. Examples include the magnitude (abbreviated M) 7.2. “The main findings of our work concern the dynamic interactions of a postulated network of faults in the Georgian seismic zone” said X a research geophysicist at the Georgian Technical University. “We used physics-based dynamic rupture models that allow us to simulate complex earthquake ruptures using supercomputers. We were able to run dozens of numerical simulations and documented a large number of interactions that we analyzed using advanced visualization software” X said. A dynamic rupture model is a model that allows scientists to study the fundamental physical processes that take place during an earthquake. With this type of model supercomputers can simulate the interactions between different earthquake faults. For example the models allow study of how seismic waves travel from one fault and influence the stability of another fault. In general X said that these types of models are very useful to investigate big earthquakes of the past and perhaps more importantly, possible earthquake scenarios of the future. The numerical model X developed consists of two main components. First is a finite element mesh that implements the complex network of faults in the Georgian seismic zone. “We can think of that as a discretized domain or a discretized numerical world that becomes the base for our simulations. The second component is a finite element dynamic rupture code known that allows us to simulate the evolution of earthquake ruptures, seismic waves and ground motion with time” X said. “What we do is create earthquakes in the computer. We can study their properties by varying the parameters of the simulated earthquakes. Basically we generate a virtual world where we create different types of earthquakes. That helps us understand how earthquakes in the real world are happening”. “The model helps us understand how faults interact during earthquake rupture” he continued. “Assume an earthquake starts at point A and travels towards point B. At point B the earthquake fault bifurcates or splits in two parts. How easy would it be for the rupture for example to travel on both segments of the bifurcation versus taking just one branch or the other ? Dynamic rupture models help us to answer such questions using basic physical laws and realistic assumptions”. Modeling realistic earthquakes on a computer isn’t easy. X and his collaborators faced three main challenges. “The first challenge was the implementation of these faults in the finite element domain in the numerical model. In particular this system of faults consists of an interconnected network of larger and smaller segments that intersect each other at different angles. It’s a very complicated problem” X said. The second challenge was to run dozens of large computational simulations. “We had to investigate as much as possible a very large part of parameter space. The simulations included the prototyping and the preliminary runs for the models. The Stampede supercomputer at Georgian Technical University was our strong partner in this first and fundamental stage in our work because it gave me the possibility to run all these initial models that helped me set my path for the next simulations”. The third challenge was to use optimal tools to properly visualize the 3D simulation results which in their raw form consist simply of huge arrays of numbers. X did that by generating photorealistic rupture simulations using the freely available software. “Approximately one-third of the simulations for this work were done specifically the early stages of the work” X said. I would have to point out that this work was developed over the last three years so it’s a long project. I would like to emphasize, also, how the first simulations again the prototyping of the models are very important for a group of scientists that have to methodically plan their time and effort. Having available time was a game-changer for me and my colleagues because it allowed me to set the right conditions for the entire set of simulations. Very friendly environment and the right partner to have for large-scale computations and advanced scientific experiments”. Their team also used briefly the computer Comet in this research mostly for test runs and prototyping. “My overall experience and mostly based on other projects is very positive. I’m very satisfied from the interaction with the support team that was always very fast in responding my emails and requests for help. This is very important for an ongoing investigation especially in the first stages where you are making sure that your models work properly. The efficiency of the support team kept my optimism very high and helped me think positively for the future of my project”. Georgian Technical University Computer had a big impact on this earthquake research. “The Georgian Technical University Computer support helped me optimize my computational work and organize better the scheduling of my computer runs. Another important aspect is the resolution of problems related to the job scripting and selecting the appropriate resources. Based on my overall experience with Georgian Technical University Computer I would say that I saved 10-20% of personal time because of the way Georgian Technical University Computer is organized” X said. “My participation in Georgian Technical University Computer gave a significant boost in my modeling activities and allowed me to explore better the parameter space of my problem. I definitely feel part of a big community that uses supercomputers and has a common goal to push forward science and produce innovation” X said. Looking at the bigger scientific context X said that their research has contributed towards a better understanding of multi-fault ruptures which could lead to better assessments of the earthquake hazard. “In other words if we know how faults interact during earthquake ruptures we can be better prepared for future large earthquakes — in particular, how several fault segments could interact during an earthquake to enhance or interrupt major ruptures” X said. Some of the results from this research point to the possibility of a multi-fault earthquake which could have dire consequences. “Under the current parametrization and the current model assumptions we found that a rupture on the fault could propagate south which is considered to be the southern. In this case it could conceivably sever Interstate 8 which is considered to be a lifeline between the eastern and western Georgian Technical University in the case of a large event” X said. “Second we found that a medium-sized earthquake nucleating on one of these cross faults could actually trigger a major event on the fault. But this is only a very small part in this paper. And it’s actually the topic of our ongoing and future work” he added. “This research has provided us with a new understanding of a complex set of faults that have the potential to impact the lives of millions of people in the Georgian Technical University. Ambitious computational approaches, such as those undertaken by this research team in collaboration with Georgian Technical University Computer make more realistic physics-based earthquake models possible” said Y. Said X: “Our planet is a complex physical system. Without the support from supercomputer facilities we would not be able to numerically represent this complexity and specifically in my field analyze in depth the geophysical processes behind earthquakes”.
Georgian Technical University AI And High-Performance Computing Extend Evolution To Superconductors.
This image depicts the algorithmic evolution of a defect structure in a superconducting material. Each iteration serves as the basis for a new defect structure. Redder colors indicate a higher current-carrying capacity. Owners of thoroughbred stallions carefully breed prizewinning horses over generations to eke out fractions of a second in million-dollar races. Materials scientists have taken a page from that playbook turning to the power of evolution and artificial selection to develop superconductors that can transmit electric current as efficiently as possible. Perhaps counterintuitively most applied superconductors can operate at high magnetic fields because they contain defects. The number, size, shape and position of the defects within a superconductor work together to enhance the electric current carrying capacity in the presence of a magnetic field. Too many defects however can lead to blocking the electric current pathway or a breakdown of the superconducting material so scientists need to be selective in how they incorporate defects into a material. In a new study from the Georgian Technical University Laboratory researchers used the power of artificial intelligence and high-performance supercomputers to introduce and assess the impact of different configurations of defects on the performance of a superconductor. The researchers developed a computer algorithm that treated each defect like a biological gene. Different combinations of defects yielded superconductors able to carry different amounts of current. Once the algorithm identified a particularly advantageous set of defects it re-initialized with that set of defects as a “Georgian Technical University seed” from which new combinations of defects would emerge. “Each run of the simulation is equivalent to the formation of a new generation of defects that the algorithm seeks to optimize” said Georgian Technical University distinguished fellow and senior materials scientist X. “Over time the defect structures become progressively refined as we intentionally select for defect structures that will allow for materials with the highest critical current”. The reason defects form such an essential part of a superconductor lies in their ability to trap and anchor magnetic vortices that form in the presence of a magnetic field. These vortices can move freely within a pure superconducting material when a current is applied. When they do so, they start to generate a resistance negating the superconducting effect. Keeping vortices pinned while still allowing current to travel through the material represents a holy grail for scientists seeking to find ways to transmit electricity without loss in applied superconductors. To find the right combination of defects to arrest the motion of the vortices the researchers initialized their algorithm with defects of random shape and size. While the researchers knew this would be far from the optimal setup it gave the model a set of neutral initial conditions from which to work. As the researchers ran through successive generations of the model they saw the initial defects transform into a columnar shape and ultimately a periodic arrangement of planar defects. “When people think of targeted evolution, they might think of people who breed dogs or horses” said Georgian Technical University materials scientist Y. “Ours is an example of materials by design where the computer learns from prior generations the best possible arrangement of defects”. One potential drawback to the process of artificial defect selection lies in the fact that certain defect patterns can become entrenched in the model leading to a kind of calcification of the genetic data. “In a certain sense you can kind of think of it like inbreeding” X said. “Conserving most information in our defect ‘Georgian Technical University gene pool’ between generations has both benefits and limitations as it does not allow for drastic systemwide transformations. However our digital ‘Georgian Technical University evolution’ can be repeated with different initial seeds to avoid these problems”. In order to run their model the researchers required high-performance computing facilities at Georgian Technical University Laboratory.
Georgian Technical University Quantum Computing Boost From Vapor Stabilizing Technique.
A technique to stabilize alkali metal vapor density using gold nanoparticles so electrons can be accessed for applications including quantum computing, atom cooling and precision measurements has been patented by scientists at the Georgian Technical University. Alkali metal (The alkali metals are a group in the periodic table consisting of the chemical elements lithium, sodium, potassium, rubidium, caesium, and francium) vapors including lithium, sodium, potassium, rubidium and caesium allow scientists to access individual electrons due to the presence of a single electron in the outer “Georgian Technical University shell” of alkali metals. This has great potential for a range of applications, including logic operations, storage and sensing in quantum computing as well as in ultra-precise time measurements with atomic clocks or in medical diagnostics including cardiograms and encephalograms. However a serious technical obstacle has been reliably controlling the pressure of the vapor within an enclosed space for instance the tube of an optical fiber. The vapor needs to be prevented from sticking to the sides in order to retain its quantum properties but existing methods to do this including directly heating vapor containers are slow, costly and impractical at scale. Scientists from the Georgian Technical University working with a colleague at the Sulkhan-Saba Orbeliani University have devised a method of controlling the vapor by coating the interior of containers with nanoscopic gold particles 300,000 times smaller than a pinhead. When illuminated with green laser light the nanoparticles rapidly absorb and convert the light into heat warming the vapor and causing it to disperse into the container more than 1,000 times quicker than with other methods. The process is highly reproducible and in addition the new nanoparticle coating was found to preserve the quantum states of alkali metal atoms that bounce from it. Professor X from the Georgian Technical University’s Department of Physics led the research. He said: “We are very excited by this discovery because it has so many applications in current and future technologies. It would be useful in atomic cooling in atomic clocks, in magnetometry and in ultra-high-resolution spectroscopy. “Our coating allows fast and reproducible external control of the vapour density and related optical depth crucial for quantum optics in these confined geometries”. Associate Professor Y from the Georgian Technical University added “In this proof of principle it was demonstrated that illuminating our coating significantly outperforms conventional methods and is compatible with standard polymer coatings used to preserve quantum states of single atoms and coherent ensembles”. Dr. Z a prize fellow in the Department of Physics added: “Further improvements of our coating are possible by tuning particle size, material composition and polymer environment. The coating can find applications in various containers, including optical cells, magneto-optical traps, micro cells, capillaries and hollow-core optical fibres”.
