Scientists say they’ve debunked Google’s claims about quantum supremacy once and for all

A team of scientists in China claims to have replicated the performance of Google’s Sycamore quantum computer using traditional hardware, undermining the suggestion that the company has achieved quantum supremacy.

As reported by Science magazine, the scientists used a system made up of 512 GPUs to complete the same computation developed by Google to show it had reached the quantum domination milestone in 2019.
