Title: Quantum energetics: from measurement powered engines to the energetics of quantum technologies

Abstract: Quantum energetics is an emerging field exploring the relationships between energy, information and entropy at quantum scales – yielding exciting questions e.g. “At the quantum level, the laws of physics are reversible, so is there anything like quantum irreversibility?” “In quantum physics, measuring can put systems in motion – so can I fuel a quantum engine, just by looking at it?”. In this colloquium, I will present the bases of the field and how it relates to thermodynamics. I will finally present how quantum energetics may contribute to keep in check the energy cost of emerging quantum technologies.
