If the paper is a little dry but you are interested in the concept of axiomatically deriving quantum theory, try this wonderful written lesson from Scott Aaronson: http://www.scottaaronson.com/democritus/lec9.html http://www.scottaaronson.com/democritus/lec9.html The lecture is part of his course, "Quantum Computing Since Democritus," which features some of the clearest prose you will find anywhere on topics like complexity theory and P vs. NP.
