Not a book, but it's a 70 page paper that changed (substantially) the way I thought about computing systems: Non-Abelian Anyons and Topological Quantum Computation. The gist is a model of computation based on knotting the worldlines of a certain kind of particle (well, particle/anti-parricle pairs) and measuring properties of the knots/links. It's also the theory behind Microsoft's effort to build a quantum computer. Highly recommend at least reading the non-technical sections (ie, everything but section 3 and appendix A).
