Quantum thermodynamics for quantum computers (and vice-versa)

A major technological obstacle on the road towards the development of effective quantum computers is represented by thermal noise. Quantum thermodynamics provides promising methods to tame it and master energy exchanges in quantum devices.  In addition, quantum computers themselves can help refining the understanding of quantum thermodynamic phenomena.  This gives origin to a virtuous cycle of mutual improvement. In this talk I will illustrate how quantum computers have been (and can be) used to verify theoretical quantum thermodynamic predictions [1], and how quantum thermodynamic predictions can in turn help quantifying and mastering dissipation in a quantum computer [2,3].
