Distinguishability of Gaussian states in quantum cryptography using postselection

Weedbrook, Christian; Alton, Daniel; Symul, Thomas; Lam, Ping Koy; Ralph, Timothy Cameron


We consider the distinguishability of Gaussian states from the viewpoint of continuous-variable quantum cryptography using postselection. Specifically, we use the probability of error to distinguish between two pure coherent (squeezed) and two particular
