> describes quantum computers as devices that perform calculations simultaneously across parallel universes That's a completely valid interpretation shared by many physicists and quantum computer scientists. Media often misinterprets this to mean that the result is available instantly in one step, but actually we have to interfere those "worlds" to get the result with some algorithmic complexity that is unavoidable to quantum computers
