Abstract

The sufficient condition of entanglement enhanced classical capacity is given for Pauli memory channel with arbitrary channel parameters. The condition is also necessary in some special cases but fails to be necessary in general. The perturbation theory is applied to verify the optimal state proposed by numerical calculation.
