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…

Quantum Cloud Computing With Self-check
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists first simulated the spontaneous formation of a pair of elementary particles with a digital quantum computer at the University of Innsbruck. Due to the error rate, however, more complex simulations would require a…
Physicists Create Prototype Superefficient Memory for Future Computers
Researchers from the Moscow Institute of Physics and Technology and their colleagues from Germany and the Netherlands have achieved material magnetization switching on the shortest timescales, at a minimal energy cost. They have thus developed a prototype of energy-efficient data storage devices. The paper was published in the journal Nature. The rapid development of information…
Research Group Uses Supercomputing to Target the Most Promising Drug Candidates From a Daunting Number of Possibilities
Identifying the optimal drug treatment is like hitting a moving target. To stop disease, small-molecule drugs bind tightly to an important protein, blocking its effects in the body. Even approved drugs don’t usually work in all patients. And over time, infectious agents or cancer cells can mutate, rendering a once-effective drug useless. A core physical…
Argonne Scientists Further Physics With Supercomputing, Prepare for Delivery of First U.S. Exascale System
James Proudfoot regularly shares his technical expertise for significant global scientific endeavors. To date, his efforts have supported many projects at Fermilab, his current home base at Argonne National Laboratory, and CERN’s Large Hadron Collider Project (LHC). At CERN in 2012, Proudfoot assisted the team in their successful pursuit of the Higgs Boson. Today, he…
Integrating Scientific Computing Into Science Curricula
With guidance from the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, nearby Adelphi University just added a new minor in scientific computing—the use of computers to solve real-world science problems. Students enrolled in the minor will begin taking classes this fall, and the hope is that they will join the computing workforce of the…
Quantum World-First: Researchers Reveal Accuracy of Two-Qubit Calculations in Silicon
For the first time ever, researchers have measured the fidelity—that is, the accuracy—of two-qubit logic operations in silicon, with highly promising results that will enable scaling up to a full-scale quantum processor. The research, carried out by Professor Andrew Dzurak’s team in UNSW Engineering, was published today in the world-renowned journal Nature. The experiments were performed…
Researchers Train a Neural Network to Study Dark Matter
As cosmologists and astrophysicists delve deeper into the darkest recesses of the universe, their need for increasingly powerful observational and computational tools has expanded exponentially. From facilities such as the Dark Energy Spectroscopic Instrument to supercomputers like Lawrence Berkeley National Laboratory’s Cori system at the National Energy Research Scientific Computing (NERSC) facility, they are on…
Generating High-quality Single Photons for Quantum Computing
MIT researchers have designed a way to generate, at room temperature, more single photons for carrying quantum information. The design, they say, holds promise for the development of practical quantum computers. Quantum emitters generate photons that can be detected one at a time. Consumer quantum computers and devices could potentially leverage certain properties of those photons as…
NCSA Scientist Employs Supercomputer Simulations in Ohio Gerrymandering Case
Computing Faster With Quasi-particles
Majorana particles are very peculiar members of the family of elementary particles. First predicted in 1937 by the Italian physicist Ettore Majorana, these particles belong to the group of so-called fermions, a group that also includes electrons, neutrons and protons. Majorana fermions are electrically neutral and also their own anti-particles. These exotic particles can, for…
Researchers Take a Step Toward Light-based, Brain-like Computing Chip
A technology that functions like a brain? In these times of artificial intelligence, this no longer seems so far-fetched—for example, when a mobile phone can recognize faces or languages. With more complex applications, however, computers still quickly come up against their own limitations. One of the reasons for this is that a computer traditionally has…
