Quantum computers can outpace our fastest classical computers in very specific areas, a groundbreaking experiment suggests.

D-Wave's claim that its quantum computers can solve problems that would take hundreds of years on classical machines have been undermined by two separate research groups showing that even an ordinary ...

A team of experts working on Google's Sycamore machine said their quantum system had executed a calculation in 200 seconds that would have taken a classic computer 10,000 years to complete.

Google's Sycamore and China's Zuchongzhi research teams have been competing with each other to build the world's best quantum computer. "We have successfully executed a larger scale random circuit ...
