Strong converse for the classical capacity of optical quantum communication channels [PDF]
, 2015 We establish the classical capacity of optical quantum channels as a sharp transition between two regimes---one which is an error-free regime for communication rates below the capacity, and the other in which the probability of correctly decoding a ...
