Quantum computation done in done multiple universes is the explanation given by David Deutsch the father of Quantum Computing. He invented the idea of a quantum computer to test the idea of parallel universes. If you are okay with a single universe coming to existence out of nothing you should be able to handle parallel universes as well just fine. Also your comment does not have any useful information. You assumed hype as the reason why they mentioned parallel computing. It's just a bias you have on looking at world. Hype does helps explain a lot of things. So it can be tempting to use it as a placeholder for anything that you don't accept based on your current set of beliefs.

I disagree that it is "the best explanation we have". It's a nice theory, but like all theories in quantum foundations / interpretations of quantum mechanics, it is (at least currently) unfalsifiable. I didn't "assume" hype, I hypothesized it based on the evidence before me: There is nothing in Google's paper that deals with interpretations of quantum mechanics. This only appears in the blog post, with no evidence given. And there is nothing google is doing with it's quantum chip that would discriminate between interpretations of QM, so it is simply false that "It lends credence to ... parallel universes" over another interpretation.

  From what I understand, David Deutsch invented the idea of quantum computer as a way to test Parallel Universes. And later people went on and built the quantum computer. Are you saying that the implementation of a quantum computer does not require any kind of assumption on computations being run in parallel universes?

    It's just not how it works. All this type of quantum computer can do is test some of the more dubious objective collapse theories. Those are wrong anyway, so all theories that are still in the running agree.

    In short, no.

    That's right, it doesn't. The implementation of a quantum computer does not prove or disprove the existence of parallel universes.

If you are okay with a single universe coming to existence out of nothing you should be able to handle parallel universes as well just fine. We have evidence for this universe though.

  I believe their point was that, if you accept the reality of _this_ universe being created from nothing, why wouldn't you also accept the notion of _other_ universes similarly existing too. I can get on board with that: that there may be other, distinct universes, but I do not understand how this would lead to the suggestion they would be necessarily linked together with quantum effects.

    Disagree with that. The fact that we reasonably accept a well-proven theory (ie the observed universe exists) that has some unexplained parts (we don't currently have a reasonable explanation for where does that universe comes from) doesn't mean that we should therefore accept any unproven theory, especially a unfalsifiable one.

I can handle it, sure, and the idea of the multiverse is attractive to me from a philosophical standpoint. But we have no evidence that there are any other universes out there, while we do have plenty of evidence that our own exists. Just because one of something exists, it doesn't automatically follow that there are others.
