    Why such cynicism in the comments? This is a pretty cool achievement, even if it's incremental or lacks present application (I'm not qualified to say either way).

    I'm cheering them on!

    Sabine Hossenfelder has a good summary of the state of Quantum Computing so far:

    How do we reconcile between these kinds of news and that Quantum Physicist who says that Quantum computers never will amount to anything? I'm confused ...

    There's something unsettling about them calling these "quantum computers." There's too much noise for them to be actually usable. It's as if someone constructed one half of an abacus and started calling it "abacus." It just doesn't feel right.

    And when we actually build a quantum computer (which, I hope, happens by the end of this century), everybody will be too bored about it.

    Can it do anything faster than a traditional supercomputer yet?

    Does it calculate generic Shore?

    i've lost interest in the qubit race.

    what can this machine do productively?
