A new experiment using Google’s Sycamore quantum processor has taken a bold step toward testing ideas from quantum gravity. For the first time, researchers successfully sent quantum information ...

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 ...

For all the hype surrounding quantum computers, the technology can sometimes appear to be a solution in search of a problem. Scientifically impressive, but not yet obviously useful in the real world.

For the past year, I kept bringing the same story to my editor: quantum computers are on the edge of becoming useful for scientific discovery. Of course, that has always been the goal. The idea of ...
