谷歌的量子计算机才是国际笑话:

If the quantum computing era dawned 3 years ago, its rising sun may have ducked behind a cloud. In 2019, Google researchers claimed they had passed a milestone known as quantum supremacy when their quantum computer Sycamore performed in 200 seconds an abstruse calculation they said would tie up a supercomputer for 10,000 years. Now, scientists in China have done the computation in a few hours with ordinary processors. A supercomputer, they say, could beat Sycamore outright.
“I think they’re right that if they had access to a big enough supercomputer, they could have simulated the … task in a matter of seconds,” says Scott Aaronson, a computer scientist at the University of Texas, Austin.
Aaronson也出来揭批了。谷歌吹牛说别人要算一万年,结果中国人只需几十秒钟:
On a supercomputer, the computation would take a few dozen seconds, Zhang says—10 billion times faster than the Google team estimated.
