I only recently 'discovered' this quantum computer buisness and quantum information. As I see it, this seems like a drastic departure from regular 'classical' computers. So if we ever get to the point of using these computers, won´t they have to rediscover the entire field of computer-science? The memory works completely different, so all algorithms must change? Just look at this stuff, it's crazy, called Shors algorithm, it only factors an integer into it's prime components. http://en.wikipedia.org/wiki/Shor's_algorithm I've only learned introduction to Quantum Mechanics, but still I don´t understand half of this stuff.
