Query: Irreversibility mitigation in unital non-Markovian quantum evolutions   The relation between the thermodynamic entropy production and non-Markovian
evolutions is matter of current research. Here, we study the behavior of the
stochastic entropy production in open quantum systems undergoing unital
non-Markovian dynamics. In particular, for the family of Pauli channels we show
that in some specific time intervals both the average entropy production and
the variance can decrease, provided that the quantum dynamics fails to be
P-divisible. Although the dynamics of the system is overall irreversible, our
result may be interpreted as a transient tendency towards reversibility,
described as a delta peaked distribution of entropy production around zero.
Finally, we also provide analytical bounds on the parameters in the generator
giving rise to the quantum system dynamics, so as to ensure irreversibility
mitigation of the corresponding non-Markovian evolution.
