Looking a bit like a bowl of spaghetti, this map shows the general scheme of the US stock market — formally known as the National Market System — as described by a team of scientist at the University of Vermont and The MITRE Corporation. Spread out between four communities in northern […]

Researchers from MIT, Google, and elsewhere have designed a novel method for verifying when quantum processors have accurately performed complex computations that classical computers can’t. They validate their method on a custom system (pictured) that’s able to capture how accurately a photonic chip (“PNP”) computed a notoriously difficult quantum problem. […]

Researchers have created a new open-source data-management system for scientists, with the hope that the system might make collaboration easier. Simplifying How Scientists Share Data Data is often at the heart of science – researchers track velocities, measure light coming from stars, analyze heart rates and cholesterol levels and scan […]

When satellites break, which is surprisingly often, there isn’t much you […]

Google announced this fall to much fanfare that it had demonstrated “quantum supremacy” – that is, it performed a specific quantum computation far faster than the best classical computers could achieve. IBM promptly critiqued the claim, saying that its own classical supercomputer could perform the computation at nearly the same speed […]

A joint research team from Google Inc., NASA Ames Research Center, and the Department of Energy’s Oak Ridge National Laboratory has demonstrated that a quantum computer can outperform a classical computer at certain tasks, a feat known as quantum supremacy. Quantum computers use the laws of quantum mechanics and units […]

Google researchers in Santa Barbara, California, say their advance may lead to near-term applications of quantum computers. ISTOCK.COM/JHVEPHOTO *Update, 23 October, 5:40 a.m.: A study from Google claiming quantum supremacy, accidentally leaked online last month, has now been published in Nature. The Google group reiterates its claim that its 53-qubit computer performed, in 200 […]

Researchers at Google finally seem to have a quantum computer that can outperform a classical computer. Here’s what that really means. ILLUSTRATION: JAMES O’BRIEN/QUANTA MAGAZINE A recent paper from Google’s quantum computing lab announced that the company had achieved quantum supremacy. Everyone has been talking about it, but what does it all mean? In […]

UMass Amherst researchers develop powerful new memory-compacting system: Introducing ‘mesh,’ memory-saving plug-in to boost phone and computer performance. Applications like web browsers or smartphone apps often use a lot of memory. To address this, a research group co-led by Emery Berger, a professor of computer science at the University of […]
