That doesn't make as much sense as it sounds like it does.
From a macro point of view the multiple worlds are all identical. All. The business with hitler doing something different in a different world is nonsense, quantum uncertainty almost never has any effect in the macro world.
So when you are computing in your world, everyone is doing the same computation in all the worlds.
Part of the MWI is that each world has a slightly different version of the event, and you just see yours, which was effected by theirs. But in a quantum computer you specifically set it up so that your get a single right answer - but if you get just one answer, all the worlds are the same, so how do you get multiple worlds each working on it?
