Hlelo-

A leaked paper suggests that Google has achieved a milestone known as quantum supremacy, using a quantum computer to perform a calculation that couldn’t be achieved even with the world’s most powerful supercomputers.

The calculation in question serves no practical purpose and is designed to be difficult for classical computers,

The researchers used it to perform a series of operations in 200 seconds that would take a supercomputer about 10,000 years to complete.

JorgeV, thanks for that article. It's refreshingly free of hype, and puts the achievement in a new perspective. As an overview of the current state of the art, it dovetails well with the current Wikpedia article on the topic...

Sounds like it's going to be more of a slow evoluation than a suddent breakthrough before we have general purpose quantum computers.

It's also not clear that Google really is ahead. IBM most likely have an alternative approach for good reason.

Google is claiming "quantum supremacy" over conventional computing devices, claiming that a processor it's developed is so much faster it's way ahead.

The technology giant's Sycamore quantum processor was able to perform a specific task in 200 seconds that would take the world's best supercomputers 10,000 years to complete.

IBM, also working on quantum computing, dispels some of the extreme claims, but agrees that quantum computing should be much faster than traditional processors.

Do you believe in magic?

Neither do I.
