quantum computers within months?

An interesting article on Google's quantum computer research:
https://interestingengineering.com/goog ... -in-months

We won't have a desktop quantum computer anytime soon, nor do we need that much power for a home computer, but there may be a practical quantum computer for high-end research in the not too distant future.

Whatever happened to the Israelis and the Chinese already having working quantum computers for research?

We have right now semi-quantum computers already (depending on who you talk to) manufactured by a company called D-Wave. They're based out of Vancouver. Some people argue that they're not -really- quantum computers, but something nearby. The company I work for handled a few shipments of them down south to NASA a year or three back.

I remember a few years back that a lot of expectation was that quantum computers would be the size of supercomputers, and I read an article last year that gave something like 6 reasons why a true quantum computer will never be larger than a car, and will quickly become much smaller.

I wish I'd bookmarked that article.

With quantum mechanics and entangled particles of these computers on my mind, I just happened to stumble on an article about entangled time: https://www.sciencealert.com/if-you-tho ... oakyr1QKTE

I'd argue D-Wave is very much not a quantum computer. Its architecture can be efficiently classically simulated, which means every problem D-Wave can solve, your toaster can solve it as well.

There are true quantum computers, their size is just very, very limited so far, and scaling them up is hard. No platform seems to have found the winning solution there.
