> quantum computers work because they aren't branching.

Or rather, the branch universes diverge and do their computing in parallel, and then finish by matching perfectly, with all universes having the same answer. Any interference from the environment outside of the qubits results in the universes not being perfectly similar at the end and you don’t get an answer back.

Question: where does the hidden variable/pilot wave interpretation say that the computation in a quantum computer takes place? Many-worlds says that it takes place in parallel universes.
