To find a solution, Li teamed up with PNNL scientists Johannes Mülmenstädt, Margaret Cheung, Gregory Schenter, and Jaehun Chun as well as Xiaolong Yin from the Colorado School of Mines and PNNL joint appointee and University of Toronto professor Nathan Wiebe. Together, they devised a mathematical solution to simulate fluid dynamics—including turbulence—using quantum computing. Their results, published in Physical Review Research, could be used to clarify some of the most prominent uncertainties in atmospheric science and beyond.

Researchers have pioneered the use of parallel computing on graphics cards to simulate acoustic turbulence. This type of simulation, which previously required a supercomputer, can now be performed on a standard personal computer. The discovery will make weather forecasting models more accurate while enabling the use of turbulence theory in various fields of physics, such as astrophysics, to calculate the trajectories and propagation speeds of acoustic waves in the universe. The research, supported by a from the Russian Science Foundation (RSF), was in Physical Review Letters.

A research team coordinated by the Department of Physics was able to work on the powerful computers of Google's Quantum Artificial Intelligence Lab to conduct a study on confinement in lattice gauge theory. The results of the study have been published in Nature Physics.

Researchers at the University of Chicago Pritzker School of Molecular Engineering have realized a new design for a superconducting quantum processor—aiming at a potential architecture for the large-scale, durable devices the quantum revolution demands.

The physicist typically uses high-performance computers to run JUQCS. This is software that can be used to simulate universal quantum computers. These machines use the exotic rules of the quantum world to solve specific tasks faster than a supercomputer – at least in theory.

The magnetic moment of the muon is an important precision parameter for putting the Standard Model of particle physics to the test. After years of work, the research group led by Professor Hartmut Wittig of the PRISMA+ Cluster of Excellence at Johannes Gutenberg University Mainz (JGU) has calculated this quantity using the so-called lattice quantum chromodynamics method (lattice QCD method). Their result, which was recently published, agrees with the latest experimental measurements, in contrast to earlier theoretical calculations. After the experimental measurements had been pushed to ever higher precision in recent years, attention had increasingly turned to the theoretical prediction and the central question of whether it deviates significantly from the experimental results and thus provides evidence for the existence of new physics beyond the Standard Model.

Researchers at the UChicago Pritzker School of Molecular Engineering (UChicago PME) have realized a new design for a superconducting quantum processor, aiming at a potential architecture for the large-scale, durable devices the quantum revolution demands.

Though seemingly inevitable, noise in quantum hardware can be tackled by so-called logical qubits – collections of tens, hundreds or even thousands of actual physical qubits that allow the correction of noise-induced errors. Logical qubits are the holy grail of quantum computing, and quantum hardware builder Infleqtion today published groundbreaking work that used the NVIDIA CUDA-Q platform to both design and demonstrate an experiment with two of them.

Multiverse Computing, a global leader in value-based quantum and quantum-inspired AI software solutions, today announced an investment from the largest Italian investor in venture capital CDP Venture Capital Sgr, as part of the company’s Series A round. The investment was carried out through two compartments of the Corporate Partners I fund, ServiceTech and Energytech, a corporate venture capital fund participated by some of the main Italian corporates as limited partners, including Baker Hughes, BNL BNP Paribas, Edison, GPI, Italgas, Snam and Terna Forward. Financial details of the investment were not disclosed.

A team of physics educators from Italy, Hungary, Slovenia and Germany is focusing on a new approach to teaching quantum physics in schools. Traditional classroom teaching has tended to focus on presenting the history of the origins of quantum physics, which often poses problems for learners. Using the quantum measurement process as an example, the researchers have now published their first empirical findings on learning quantum physics – based on two-state systems – in the international journal Physical Review Physics Education Research.
