Quantum Computer Solves Decades-Old Problem Three Million Times Faster Than a Classical Computer

ZDNet reports: Scientists from quantum computing company D-Wave have demonstrated that, using a method called quantum annealing, they could simulate some materials up to three million times faster than it would take with corresponding classical methods. Together with researchers from Google, the scientists set out to measure the speed of simulation in one of D-Wave’s quantum annealing processors, and found that…

Lack of symmetry in qubits can’t fix errors in quantum computing, might explain matter/antimatter

A team of quantum theorists seeking to cure a basic problem with quantum annealing computers—they have to run at a relatively slow pace to operate properly—found something intriguing instead. While probing how quantum annealers perform when operated faster than desired, the team unexpectedly discovered a new effect that may account for the imbalanced distribution of matter and antimatter in the universe…

Swiss Company Claims Weakness Found in Post-Quantum Encryption, Touts Its New Encryption Protocol

“A Swiss technology company says it has made a breakthrough by using quantum computers to uncover vulnerabilities in commonly used encryption,” reports Bloomberg: Terra Quantum AG said its discovery “upends the current understanding of what constitutes unbreakable” encryption… Terra Quantum AG has a team of about 80 quantum physicists, cryptographers and mathematicians, who are based in Switzerland, Russia, Finland and the…

The Next Graphene? Shiny and Magnetic, a New Form of Pure Carbon Dazzles

sciencehabit quotes Science magazine: A “happy accident” has yielded a new, stable form of pure carbon made from cheap feedstocks, researchers say. Like diamond and graphene, two other guises of carbon, the material seems to have extraordinary physical properties. It is harder than stainless steel, about as conductive, and as reflective as a polished aluminum mirror. Perhaps most surprising, the substance…
