Google has unveiled a new chip which it claims takes five minutes to solve a problem that would currently take the world's fastest super computers ten septillion – or 10,000,000,000,000,000,000,000,000 years – to complete.

Its director, Michael Cuthbert, told the BBC he was wary of language that fuelled the "hype cycle" and thought Willow was more a "milestone rather than a breakthrough".

Frustrating that the article seems to pretty heavily focus on pop sci talk about quantum rather than actual point of what they've made. The actual news being methods that "present device performance that, if scaled, could realize the operational requirements of large scale fault-tolerant quantum algorithms."
