- Abstract: A universal characterization of non-Markovianity for any open hybrid quantum
systems is presented. This formulation is based on the negativity volume of the
generalized Wigner function, which serves as an indicator of the quantum
correlations in any composite quantum systems. It is shown, that the proposed
measure can be utilized for any single or multi-partite quantum system,
containing any discrete or continuous variables. To demonstrate its power in
revealing non-Markovianity in such quantum systems, we additionally consider a
few illustrative examples.
