Task that would take most powerful supercomputer 10,000 years ‘completed by quantum machine in minutes’
For Google it was a historic announcement: a declaration that it had won the race to achieve “quantum supremacy” – the moment that a futuristic quantum computer performed a task that stumped even the most powerful standard computer in the world.
But for all the fanfare, which saw Google’s CEO Sundar Pichai compare the feat to building the first rocket to reach space, the claim has sparked a bunfight. The tech firm’s rival, IBM, was swift to dismiss the excitement. Google has not, it asserts, achieved the highly prized goal of quantum supremacy.
