Google has announced its quantum processor that is able to do what used to take 10,000 year in just 200 seconds.
I am not knowledgeable enough to judge the validity of this claim, but IBM, for instance, says the job only takes 2.5 days on conventional computer...
Maybe a real breakthrough is achieved since it is now published in Nature with a claim of "quantum supermacy" achieved.


And yes it is 42!

Yikes, just learned IBM was talking about the "Summit supercomputer" when they said it takes 2.5 days... salty much?!
Ofcourse since they built Summit, they want to use this opportunity to divert undeserved attention to Summit instead of the real
breakthrough -- if that indeed what it is.

Thanks.

They say they are still (just?) a decade away from real world applications.

PS: that is how 53 qubit look like....

2.5 days is 216,000 seconds, so still a good speed up.

Unfortunately, chess is MUCH too big a problem to model on today's quantum computers.

I wouldn't trust a Google announcement as far as I could throw it. Sounds like their marketing department is at it again.

Wasn't there such an announcement by Google just a month ago, and a disclaimer followed ?

the paper was published on NASA's site and immediately removed (probably because it was not yet peer-reviewed?)

One thing is for sure, you can not stop the race for Quantum Computer Supremacy with China and the US (and Europe?) investing in technology for quantum computer based decryption methods (Shor's algorithm).

Step #1 is to create a quantum chess algorithm.

For example, Shor's algorithm is the quantum algorithm for factoring large numbers: https://en.wikipedia.org/wiki/Shor%27s_algorithm. Quantum computers aren't "faster", they just allow for some operations that don't exist in traditional computers. As such, quantum computers might be faster, in some cases.

I also do not trust Google.
