Dynamics of coherence-induced state ordering under Markovian channels

Quantum Physics 2018-05-11 v1

Abstract

We study the dynamics of coherence-induced state ordering under incoherent channels, particularly four specific Markovian channels: - amplitude damping channel, phase damping channel, depolarizing channel and bit flit channel for single-qubit states. We show that the amplitude damping channel, phase damping channel, and depolarizing channel do not change the coherence-induced state ordering by l1l_1 norm of coherence, relative entropy of coherence, geometric measure of coherence, and Tsallis relative α\alpha-entropies, while the bit flit channel does change for some special cases.
