Quantum information in minimal quantum thermal machines — •Géraldine Haack — University of Geneva, Switzerland

Minimal models for quantum thermal machines are central to understand energy exchanges at the quantum scale and the intimate connection between quantum thermodynamics and quantum information theory. In particular, one would like to determine whether quantum features, like entanglement, interactions and quantum statistics, can be beneficial to the efficiency of a thermal machine made of few quantum constituents. This research direction becomes even more fascinating in view of recent experimental progresses towards manipulating out-of-equilibrium multi-partite quantum systems, allowing for new designs and investigations of quantum thermal machines. In this talk, I will present some of our latest results concerning the advantages that open quantum systems can offer towards heat and quantum information management at the nanoscale, including storing energy, generation of quantum correlations and optimization of dissipative flows.
