> What you described was very popular in the nineteenth century and still would be if we used purely Newtonian physics. But as others already pointed out, quantum information is unpredictable, if not random.


This is part of what I was getting asking, actually. If the information is only unpredictable, then *assuming that data was in the computer*, it should work. If it's random, it wouldn't. With my very fuzzy understanding of quantum mechanics, I've been under the impression that it we were just unable to measure it without changing it. I could very easily be wrong.
