Equivalence between non-Markovian dynamics and correlation backflows
Dario De Santis, Markus Johansson
The information encoded into an open quantum system that evolves under a Markovian dynamics is always monotonically non-increasing. Nonetheless, for a given quantifier of the infor…

A correlation measure detecting almost all non-Markovian evolutions
Dario De Santis, Markus Johansson, Bogna Bylicka +2
We investigate the ability of correlation measures to witness non-Markovian open quantum system dynamics. It is shown that the mutual information and any entanglement measure betwe…
