Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform classical systems on certain tasks. Over the past few decades, researchers ...

Critics of quantum computers have argued that the supposed advantage these machines have over regular computers have often relied on tests involving pointless tasks. Now, the team at Google Quantum AI ...

The original version of this story appeared in Quanta Magazine. For computer scientists, solving problems is a bit like mountaineering. First they must choose a problem to solve—akin to identifying a ...
