When Thermodynamics Meets Quantum Optics

Location: 14 Sir Christopher Ondatjee Avenue (E7B) T5

Professor Alexia Auffèves, Institut Néel of Grenoble, France

Quantum thermodynamics is a young and active field of research that is currently developing at the interface between quantum information, quantum optics and stochastic thermodynamics. The questions it raises are various, and range from the very fundamental (what is time arrow at the quantum scale?) to the fairly practical (how much energy should I spend to perform a quantum computation?) After reviewing the main motivations of the field, I will present a proposal to develop a new kind of genuinely quantum engine. The device operates in the absence of any hot source: It extracts energy from quantum measurement only, and is doable with state of the art superconducting circuits. It evidences that quantum measurement and decoherence have an energetic footprint that is bound to impact the energetic cost of quantum information technologies.

Alexia Auffèves is a senior CNRS researcher working at the Institut Néel of Grenoble, France. Her fields of expertise are quantum optics, quantum thermodynamics, quantum information and quantum foundations.
