alt Hacker NewsQuantum 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 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.

We have evidence for this universe though.
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.
