[cryptography] quantum key distribution

  1. Nov 26, 2009 #1
    I'm reading up on quantum key distribution schemes, mostly: BB84, B92 and the EPR Protocol, and I'm having some problems relating them.

    Is it correct to say that BB84 is a special case of B92(with extra specific states)? Is it also safe to say that both BB84 and B92 are special cases of EPR Protocol(with its entanglement being the most flexible possible)?

    Anyone happen to know of a nice comparison? Theres a nice selection online for BB84, not much for B92 or the EPR Protocol unfortunately.

    Thanks
