Google's quantum computer has achieved a verifiable calculation that classic computers cannot, a team of researchers claim.
The work, reported on October 22 in Nature, could point to future applications, as verification is an essential step toward potential applications of quantum computers.
"If I can't prove to you that the data is correct, how can I do anything with it?"
physicist Tom O'Brien of Google Quantum AI in Santa Barbara, Calif., said. The result of the calculation could be verified by another quantum computer, although it hasn't been yet.
Google's Willow quantum chip has achieved verifiable quantum advantage, a quantum calculation that's apparently out of reach for a traditional, classical computer, but with a result that can be confirmed to be correct.
