Engineering classical capacity of generalized Pauli channels with admissible memory kernels
arXiv:2109.10152 · doi:10.3390/e23111382
Abstract
We analyze the classical capacity of the generalized Pauli channels generated via the memory kernel master equations. For suitable engineering of the kernel parameters, the evolution with non-local noise effects can produce dynamical maps with higher capacity than the purely Markovian evolution. We provide instructive examples for qubit and qutrit evolution. Interestingly, similar behavior is not observed when analyzing the time-local master equations.
