Extra cost of erasure due to quantum lifetime broadening
Joe Dunlop, Federico Cerisola, Juliette Monsel +6
The energy cost of erasing a bit of information was fundamentally lower bounded by Landauer, in terms of the temperature of its environment: . However,…
Optomechanical cooling with coherent and squeezed light: the thermodynamic cost of opening the heat valve
Juliette Monsel, Nastaran Dashti, Sushanth Kini Manjeshwar +6
Ground-state cooling of mechanical motion by coupling to a driven optical cavity has been demonstrated in various optomechanical systems. In our work, we provide a so far missing t…
The energetic cost of work extraction
Juliette Monsel, Marco Fellous-Asiani, Benjamin Huard +1
We analyze work extraction from a qubit into a wave guide (WG) acting as a battery, where work is the coherent component of the energy radiated by the qubit. The process is stimula…
An autonomous quantum machine to measure the thermodynamic arrow of time
Juliette Monsel, Cyril Elouard, Alexia Auffèves
According to the Second Law of thermodynamics, the evolution of physical systems has a preferred direction, that is characterized by some positive entropy production. Here we propo…
