Abstract:
We discuss production of entropy per unit time for a quantum system
governed by the Lindblad equation. The difficulty is as follows: in order
to determine the total production of entropy, one must know the entropy
flow from the system into the environment. This requires additional
information on the environment and on its interaction with the system. The
Lindblad equation for the reduced density matrix of the system does not
contain such information. Therefore, the following question arises: What
minimum additional information about the environment must be added to the
Lindblad equation in order to find the flow of entropy into the environment
and the total production of entropy? To answer this question, we use the
concept of a complementary quantum channel known from the the quantum
information theory. We also prove a theorem on the nonnegativity of
production of entropy, and, under certain assumptions, the adiabatic and
nonadiabatic contribution to it.
Keywords:
open quantum systems, Lindblad equation, production of entropy, second law of thermodynamics.
