Mixing-induced quantum non-Markovianity and information flow / H. Breuer, G. Amato, B. Vacchini. - In: NEW JOURNAL OF PHYSICS. - ISSN 1367-2630. - 20:4(2018 Apr 12). [10.1088/1367-2630/aab2f9]
Abstract:
Mixing dynamical maps describing open quantum systems can lead from Markovian to non-Markovian processes. Being surprising and counter-intuitive, this result has been used as argument against characterization of non-Markovianity in terms of information exchange. Here, we demonstrate that, quite the contrary, mixing can be understood in a natural way which is fully consistent with existing theories of memory effects. In particular, we show how mixing-induced non-Markovianity can be interpreted in terms of the distinguishability of quantum states, system-environment correlations and the information flow between system and environment.
