Common assumptions in the theoretical description of open quantum system dynamics, such as non-Markovianity or perturbative treatments, do not hold for state-of-the-art realisations of mesoscopic quantum devices. There is a need for a consistent description of non-Markovian open quantum dynamics to form the theoretical framework for ongoing and upcoming experiments in quantum thermodynamics. Also, there is evidence that non-Markovianity can be exploited as a resource to enhance the performance of quantum thermodynamic devices [1]. To bridge the gap between an information theoretic and a thermodynamic description, we applied the information theoretic measures of non-Markovianity [2] to the quantum thermodynamic setting of a generic driven Spin-Boson model [3].
