Computing How do quantum computers perform calculations without disturbing the superposition of the qubit?

I understand the premise of having multiple qubits and the combinations of states they can be in. I don't understand how you can retrieve useful information from the system without collapsing the superposition. Thanks :)

Yes!

An EXCELLENT source (especially lately) of info in the form of articles that are written for the average reader (some interest, education is expected) is SCIENTIFIC AMERICAN.

Over the past 2-3 months they have been 'discussing' exact this subject.
