The role of quantum measurement in stochastic thermodynamics

A propos de cette vidéo

Publié le 23/01/2017 - Durée : 02H01min

I will present a new formalism to investigate stochastic thermodynamics in the quantum regime, where stochasticity and irreversibility primarily come from quantum measurement. In the absence of any bath, a purely quantum component to heat exchange, that corresponds to energy fluctuations caused by measurement back- action. Energetic and entropic signatures of measurement induced irreversibility are then investigated for canonical experiments of quantum optics, and the energetic cost of counter-acting decoherence is characterized on a simple state-stabilizing protocol. I will finally open on a new kind of genuinely quantum engines, where work is solely extracted from quantum measurement.
