    Well, since quantum cryptography devices are being sold today, there's
    little reason to wonder if quantum cryptography will ever leave the
    laboratory -- it already has done so. :)

    I still don't understand what "certain things" you mean.

    You don't? I do. If you know a theory to factor numbers in polynomial time
    (or a theory to calculate the secret key from the public key without
    factoring the modulus), by all means share it. :)
