Rebuilding quantum thermodynamics on quantum measurement
Jeudi 27 avril
à 11h, en salle C. BROT
Thermodynamics relies on randomness. In classical thermodynamics, the coupling to a thermal bath induces stochastic fluctuations on the system considered : Thermodynamic irreversibility stems from such fluctuations , which also provide the fuel of thermal engines.
Quantum theory has revealed the existence of an ultimate source of randomness : Quantum measurement through the well-known measurement postulate . In this talk I will present recent attempts to rebuild quantum thermodynamics on quantum measurement, from quantum irreversibility to quantum engines extracting work from quantum fluctuations [3,4].
