چكيده فارسي :
We Study the temporal rate of variations of the von Neumann entropy in an open quantum system. We show that for almost all initial states of the bath and the system, the time-average entropy rate is relatively small. This result holds true under fairly general conditions in almost any arbitrary quantum system, and implies that the rate of information loss in small systems coupled to a relatively larger bath is generally negligible.
