Quantum stochastic thermodynamics of macroscopic systems: an algebraic approach
Antoine Rignon-Bret, Cyril Elouard
We build a framework for the thermodynamics of macroscopic quantum systems. In contrast with approaches requiring access to the full density matrix, our framework relies on a coars…
Minimally invasive measurement of work in coherent quantum systems
Cyril Elouard, Karen Hovhannisyan, Giulia Rubino
A central challenge in quantum thermodynamics is to access work fluctuations in coherent processes without distorting the energetics of the unmeasured evolution. In standard two-po…
Weak continuous measurements require more work than strong ones
Lorena Ballesteros Ferraz, Cyril Elouard
Understanding the energy cost of quantum measurement process and its connection to the measurement performance faces the challenge of modeling the objectification process. The latt…
A refined thermodynamic analysis of nonsecular master equations
Mohamed Boubakour, Talia Szikman, Cyril Elouard
We present a systematic thermodynamic analysis of nonsecular master equations. We consider master equations resulting either from the partial secular and the geometric-arithmetic a…
Revealing the fuel of a quantum continuous measurement-based refrigerator
Cyril Elouard, Sreenath K. Manikandan, Andrew N. Jordan +1
While quantum measurements have been shown to constitute a resource for operating quantum thermal machines, the nature of the energy exchanges involved in the interaction between s…
Amplifying microwave pulses with a single qubit engine fueled by quantum measurements
Rémy Dassonneville, Cyril Elouard, Romain Cazali +4
Recent progress in manipulating individual quantum systems enables the exploration of engines exploiting non-classical resources. One of the most appealing is the energy provided b…
