In an open systems framework it was shown that the irreversible entropy production might be attributed to the total correlations between the system and the reservoir.įluctuation theorems yield exact results, valid for arbitrary nonequilibrium dynamics, and help understand the nonlinear transport of energy, heat and even information in quantum technologies. The relationship between the relative entropy of entanglement and the dissipated work may be an entanglement witness. In the nonequilibrium thermodynamics, it is critical for the formulation of irreversible entropy production in both closed and open driven quantum systems. In nonequilibrium quantum systems, the relative entropy is central due to its close relationship with the free energy of a quantum state, quantum information theory in the geometric picture of entanglement and general quantum and classical correlations. Within the thermodynamics of quantum systems and the quantum fluctuation relations research focus is the microscopic expression for entropy production.
