an interesting article here
http://www.networkworld.com/community/?q=node/8334&nwwpkg=alphadoggs says
that university researchers at harvard have created a working quantum
cryptographic matrix. now my question is this. since according to the
article quantum cryptography works with photons, and many of todays
encryption schemes use XOR, how would a quantum cryptographic scheme work
with such a function. except maybe to comparethe intensity of one photon
with the intensity of another and the result being the difference in their
respective inensities. any thoughts?
