Query: Non-Markovianity through accessible information   The degree of non-Markovianity of quantum processes has been characterized in
several different ways in the recent literature. However, the relationship
between the non-Markovian behavior and the flow of information between the
system and the environment through an entropic measure has not been yet
established. We propose an entanglement-based measure of non-Markovianity by
employing the concept of assisted knowledge, where the environment E, acquires
information about a system S, by means of its measurement apparatus A. The
assisted knowledge, based on the accessible information in terms of von-Neumann
entropy, monotonically increases in time for all Markovian quantum processes.
We demonstrate that the signatures of non-Markovianity can be captured by the
nonmonotonic behaviour of the assisted knowledge. We explore this scenario for
a two-level system undergoing a relaxation process, through an experimental
implementation using an optical approach that allows full access to the state
of the environment.
