OT: Google's quantum computer.

https://blog.google/technology/research/google-willow-quantum-chip/Willows performance on this benchmark is astonishing: It performed a computation in under five minutes that would take one of todays fastest supercomputers 1025 or 10 septillion years. If you want to write it out, its 10,000,000,000,000,000,000,000,000 years. 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.
The logic of this is difficult to follow for me: they claim that the fact that their quantum computer is so much faster than the regular computer (does something in 5min that "regular"supercomputer can only do in 10^25 years, which is roughly 1 million billion times longer than our Universe existed somehow indicates that the quantum computer uses parallel universes to do the calculations. This just does not seem right to me.
However, I can imagine the quantum computer "spawning" those universes, maybe virtually, to "help" it's calculations.
Otherwise, it is not clear to me how it managed to link up with those preexisting universes as there is nothing there that one might consider an interface.
I read the D. Deutsch book, but the argument there was just as unclear. Perhaps, I am just not getting it.
