Jumping in a little late here, but a good detailed introduction to quantum computing is presented in this paper:
An introduction to quantum computing for non-physicists. http://doi.acm.org/10.1145/367701.367709
For those without access to ACM, http://arxiv.org/abs/quant-ph/9809016 has a link to a pdf of the paper on the right side.
I discovered this paper a few years ago when I had to give a presentation on quantum computing. Be aware that you still require a decent level of maths to actually get through it all.
