The claim is that this new chip can complete a task in just five minutes that would take
10,000,000,000,000,000,000,000,000 years for some of the world’s fastest conventional computers to complete.
That's far more years than the age of the known universe.
And it's only 4cm²...

Guess I don't see how this could be a "standard benchmark computation" if it's impossible for any other system.
"Willow performed a standard benchmark computation in under five minutes that would take one of today’s
fastest supercomputers 10 septillion (that is, 1025) years — a number that vastly exceeds the age of the Universe."

It's a bit more it seems.
Must have been extrapolated.
I guess those Google guys know a thing or two about maths. 🙂
Thing is nobody knows how to put most math problems into a form that a quantum computer can work with. Also, a conventional computer may always be needed for I/O with the quantum computer.
The situation has been described like this: The quantum computing guys have a hammer and they are looking for nails (math problems that can work with quantum computers). One big limitation is that you can never ever make a copy of anything.

They will not spend billions on research without a purpose. One can say that every new technology brings dangers to be abused. E.g., hacking the most complicated passwords will be peanuts. But other applications will probably benefit greatly from it.

The test they used so far that is so impressive is completely useless for practical purposes other than benchmarking quantum computers.
That said, of course money will be spent on it and applications will be found. Doing most of math as we understand it today is still problem. A breakthrough in abstraction of math operations needs to occur so that problems can be represented in quantum computing compatible form. But, yes, quantum computers are really fast at factoring large numbers, faster than the cryptography guys had hoped.

The 1025 should be 1025, the formatting probably disappeared when copying the text from Googles blog and pasting it in here.
ie.
for superscript, 1025
and subscript, 1025
mind-boggling figures. :)
The future will tell what nefarious motives they may have for this kind of capabilities.
