If you really want to have a good (but easy) introduction to quantum mechanics (and quantum information) I recommend http://www.amazon.com/Six-Quantum-Pieces-Course-Physics/dp/9814327549 http://www.amazon.com/Six-Quantum-Pieces-Course-Physics/dp/9... - it requires nothing more than some linear algebra. (As a side note, I'm trying to make a computer game of quantum mechanics, to make people learn by playing.)
