The system remains simultaneously secure and fixed until the paper is <i>observed</i>. And we all know that that's not the same as publication. Nicko,
Don’t be silly. The system remains simultaneously secure and fixed until the paper is observed. And we all know that that’s not the same as publication.

Well, because Quantum encryption is so much more fun to try to observe! Speaking of which: If we encrypt something using quantum cryptography, and no one is around to decipher it - is it really encrypted information? “why wouldn’t you just use 256-bit conventional crypto on a pair of IPsec routers you bought at Fry’s instead?”
