Abstract
- Random unitary dynamical evolutions play an important role in characterizing quantum Markovianity. By exploiting the maximally entangled state under the representation of a set of generalized unitary Weyl operators, we present a necessary and sufficient condition for quantum Markovianity in d-level systems from the perspective of quantum mutual information. Moreover, we analyze three quantum Markovianity criteria among divisibility, BLP and LFS 0 to establish their connections and differences. It is shown that they coincide in many special cases, but different in general, and Markovianity in the sense of LFS 0 is less restrictive than Markovianities in the sense of divisibility and BLP by detailed examples.
