Quantum cryptography at SJSU

I finally managed to sneak into a class at San Jose State today. It was a graduate level class on cryptography & quantum cryptography was being introduced. The prof started out by going over the differences between classical & quantum physics, then proceeded to explain the math used to describe quantum mechanics. I noticed that I seemed to be one of the very few people in the class that was following along; the rest looked hopelessly lost. I suspect that my strong Math background courtsey of UW helped a lot as there was a considerable amount of linear algebra involved.

I was impressed by how clearly the prof was able to explain the concepts behind quantum cryptography - yes, he used Alice, Bob & Eve - once he had gone through the required quantum mechanics preamble. I certainly learned a lot in this class, especially about polarized light.
