Google's new 105-qubit "Willow" quantum processor has surpassed a key milestone first proposed in 1995 — with errors now reducing exponentially as you scale up quantum computers.
Google scientists have created a new quantum processor that, in five minutes, cracked a problem that would have taken the world's best supercomputer 10 septillion years to solve. The breakthrough will allow quantum computers to become less error-prone the bigger they get, achieving a milestone that overcomes a decades-long obstacle.
