The company has drawn governments, a major chipmaker, and the Pentagon into an effort to control fragile photons and build a useful quantum machine. It aims to be the first.

Four independent research teams report big advances in devices built with the underestimated quantum-bit technology, including lower error rates. In the fierce race ...

A new mathematical test shows that many seemingly useful quantum states can still be simulated classically, raising the bar ...

Quantum computers are expected to transform many facets of science and industry over the next decade or so – but it’s very hard for most potential users to get their hands on one to find out what they ...

Amazon AI executive Peter DeSantis told CNBC that in five-to-seven years, "we're going to start to see the first commercially useful small-scale quantum computers." DeSantis leads a new Amazon ...

To this day, we have yet to see a quantum computer conclusively perform a single useful task. Existing machines are simply too small and error-ridden to solve commercially relevant problems. That hasn ...

In a laboratory in Broomfield, Colorado, 98 atoms are suspended in mid-air, held in place by electric fields and cooled to temperatures close to absolute zero. Each atom is far smaller than anything ...
