As the race to develop large-scale, reliable quantum computers gains speed, fortification efforts are ramping up to protect digital systems from a technology that could utterly obliterate their security. Commonwealth Cyber Initiative researchers at Virginia Tech and George Mason University are developing security protocols to fend off cyberattacks — both from today’s computers and from […]

A tremendous portion of the world depends on the output of the oceans’ major fisheries, which have, in recent decades, found themselves under near-constant threat from mismanagement (e.g. overfishing). Climate change, of course, clouds the future of these fisheries even more – and now, researchers are leveraging the power of supercomputing to predict how climate […]

Researchers at the University of Rochester have recently introduced a new strategy to coherently manipulate either single or multiple electron spins in silicon quantum dots. This method, introduced in a paper published in Nature Physics, could open new possibilities for the development of reliable and highly performing quantum computers. The post New Study Achieves Coherent […]

In two papers published in Nature Communications in December, researchers from the University of Wisconsin–Madison, the University of New South Wales and TU-Delft showed that tweaking a qubit’s physical structure, known as a silicon quantum dot, creates sufficient valley splitting to reduce computing errors. The findings turn conventional wisdom on its head by showing that a […]

The immediate impacts of climate change and land-use change are severe enough, but increasingly, researchers are warning that large enough changes can then snowball into catastrophic changes. New, supercomputer-powered research from Giovanni Strona (a senior researcher with the European Commission’s Joint Research Centre, or JRC) and Corey Bradshaw (a professor at Flinders University in Australia) […]

Researchers and scientists are working together to apply AI and modeling techniques such as machine learning (ML) to advance Earth and environmental science. Specifically, a group of scientists and experts aims to integrate modern technology in the work of Earth system models, observations and theory — as well as to provide computational capabilities that can […]

Just as the sound of a guitar depends on its strings and the materials used for its body, the performance of a quantum computer depends on the composition of its building blocks. Arguably the most critical components are the devices that encode information in quantum computers. One such device is the transmon qubit — a […]

With the help of new observational data of gravitational waves and electromagnetic signatures, University of Potsdam researchers are using supercomputers to understand binary neutron star mergers. The post University of Potsdam Researchers Utilize Supercomputers to Understand Binary Neutron Star Mergers appeared first on HPCwire.

Quantum computing is coming. Though predicted decades ago and only now in its early stages, this potentially game-changing technology and the hardware and software that support it are progressing rapidly – thanks in part to dedicated initiatives like the QIS@Perlmutter project at Lawrence Berkeley National Laboratory (Berkeley Lab). The post Perlmutter Results Show Progress in Quantum […]

Using a quantum simulator, researchers at the Max Planck Institute of Quantum Optics (MPQ) have observed pairs of charge carriers that may be responsible for the resistance-free transport of electric current in high-temperature superconductors. The post Quantum Simulator Enables 1st Microscopic Observation of Charge Carriers Pairing appeared first on HPCwire.
