As Scott Aaronson points out, all those computations in "other worlds"
have to interfere in this world to produce the answer.

Hartmut Neven, would go further than I would, he thinks the fact that
his chip has solved a problem in five minutes that would take the
largest conventional supercomputer 10^25 years to solve is a direct
result of many Willow chips in many different worlds working on the
same problem at the same time. Granted it's not a problem of any
practical use but I agree with Neven that fact is not relevant in this
context.*

*/“This mind-boggling number exceeds known timescales in physics and
vastly exceeds the age of the universe. It lends credence to the
notion that quantum computation occurs in many parallel universes, in
line with the idea that we live in a multiverse, a prediction first
made by David Deutsch.”/*

*Other interpretations can give the same results but I can understand
why somebody who has to get his hands dirty and actually make the
hardware and software for a Quantum Computer would take the Many
Worlds idea as a given due to the fact that you've got to keep a whole
lot of complicated things straight in your head, and it's much easier
to do that if you think in Many Worlds terms because it doesn't need
to add all sorts of complicated bells and whistles that other quantum
interpretations require. So I would say that regardless of whether
it's true or not, in the next few years the Many Worlds interpretation
is going to increase in popularity, especially among Quantum Computer
engineers and software writers.*
