I've been feeding my curiosity in Quantum Computation with works from the great pioneer in the field - Prof. David Deutsch. It is not that I like computers but because that the ideas behind quantum computation are so fundamentally profound and far-reaching that I just can't not keep an eye on it! Read up David Deutsch's paper Physics, Philosophy and Quantum Computation for a synopsis of the promises of quantum computation and the implications of quantum constructor theory. There are a couple of other interesting papers available on his site.

If you are all-excited and orgasmic about it and can't wait to bite your teeth into it then check out the "Introduction to Quantum Computation" lectures by David Deutsch. As the page says, you should be able to follow it easily if you understand what a vector space is and what eigenvalues of a matrix are.
