Explainer: Google hails 'quantum supremacy', but don't chuck out your PC just yet

BERLIN - Researchers at Google say they have achieved ‘quantum supremacy’, in which a computer harnessing the properties of sub-atomic particles did a far better job of solving a problem than the world’s most powerful supercomputer.

According to Google, such a huge win fulfils the accepted definition of supremacy. Simply put, this entails solving a computing task that a conventional computer would struggle to, or never, complete. Combining entanglement with superposition leads to exponential increases in computing power with each additional qubit.

Google’s researchers, in solving the problem with a high degree of fidelity - or accuracy - can reasonably claim to have achieved a significant milestone, say physicists.Critics, including rival IBM, say Google is hyping its achievement and creating the misleading impression that quantum computers have effectively rendered all conventional computers obsolete.

I welcome our new computer overlords.

Wasn’t even considering it. Thanks for the heads up though, I guess?

“Quantum supremacy”? Sure that isn’t a Bond/Bourne crossover?

Does Google's claim of 'quantum supremacy' only exist if you look inside the box?

I'm more excited about Google and IBM rivalry in that field...

Seen design of the early seventies ...

Why would I chuck it out. I'm too poor to replace it.
