Dense coding capacity in correlated noisy channels with weak measurement*
Jin-Kai Li, Kai Xu, Guo‐Feng Zhang
Abstract
Capacity of dense coding via correlated noisy channel is greater than that via uncorrelated noisy channel. It is shown that the weak measurement and reversal measurement need to further improve their quantum dense coding capacity in correlated amplitude damping channel, but this improvement is very small in correlated phase damping channel and correlated depolarizing channel.
