From the FT article:

--- Quote ---Google claims to have built the first quantum computer that can carry out calculations beyond the ability of today’s most powerful supercomputers, a landmark moment that has been hotly anticipated by researchers.

A paper by Google’s researchers seen by the FT, that was briefly posted earlier this week on a Nasa website before being removed, claimed that their processor was able to perform a calculation in three minutes and 20 seconds that would take today’s most advanced classical computer, known as Summit, approximately 10,000 years.

The researchers said this meant the “quantum supremacy”, when quantum computers carry out calculations that had previously been impossible, had been achieved.

SilverSolder:
Is it available as an Arduino shield?
Bud:
Claimed by "google researchers", not verified by independent experts.  :=\
SiliconWizard:
Also just look at the "but, but" paragraph.

Supremacy my ass. :popcorn:
RoGeorge:
I believe Google, just that they probably didn't use quantum particles to do the calculations.  With quantum particles there isn't much hope to scale up the number of qubits.

It is possible to run the same type of quantum algorithms, with the same speed advantages, using something very similar with analog computing techniques and true random noise.
