Quantum Cryptography Approaching the Classical Limit
We consider the security of continuous-variable quantum cryptography as we approach the classical limit, i.e., when the unknown preparation noise at the sender’s station becomes significantly noisy or thermal (even by as much as 10 (superscript 4) times greater than the variance of the vacuum mode)....
