Hi Cetin, Thanks for your contact info. Here is some information about the things we talked about last Friday. Books that I would recommend on quantum computing (in increasing order of sophistication): * Mermin: http://www.amazon.com/Quantum-Computer-Science-David-Mermin/dp/0521876583 * Kaye, Laflamma and Mosca: http://www.amazon.com/Introduction-Quantum-Computing-Phillip-Kaye/dp/019857049X * Nielsen and Chuang: http://www.amazon.com/Quantum-Computation-Information-Michael-Nielsen/dp/0521635039 * Another one that deals mostly with quantum information theory is Loepp and Wootters: http://www.amazon.com/Protecting-Information-Classical-Correction-Cryptography/dp/0521534763 An old website of my graduate course on quantum computation is here: http://www.cs.ucsb.edu/~vandam/teaching/S07_CS290/ You can buy your own quantum random number generator from the company id Quantique http://www.idquantique.com/products/quantis.htm And yes there are gambling websites that use this for real.
