"Quantum Logic with Light, Glass, and Mirrors," by Andrew Shields. Science, 13 September 2002.
"Although only a handful of quantum algorithms have been discovered so far, they include important mathematical problems, such as finding the prime factors of large numbers, the Achilles heel of classical cryptography." From there the author predicts that because unlike every other known method quantum cryptography can guarantee the secrecy of encryption keys, it "may soon secure optical links between different sites of banks or large corporations across a metropolitan area. Thus the first applications for quantum logic are very likely to be such photonic systems."
