Irreversibility of decorrelating processes: an experimental assessment in cavity QED
Guillaume Cœuret Cauquil, Patrice A. Camati, Irénée Frerot +3
Entropy production quantifies the amount of irreversibility of a physical process, leading to fundamental bounds for thermodynamic quantities. It captures the inability to run a ph…
Thermodynamics of autonomous optical Bloch equations
Samyak Pratyush Prasad, Maria Maffei, Patrice A. Camati +2
Optical Bloch Equations (OBEs) are canonical equations describing the dynamics of a classically driven atom coupled to a thermal bath. Their thermodynamics is highly relevant to es…
Comparing the quantum switch and its simulations with energetically-constrained operations
Marco Fellous-Asiani, Raphaël Mothe, Léa Bresque +5
Quantum mechanics allows processes to be superposed, leading to a genuinely quantum lack of causal structure. For example, the process known as the quantum switch applies two opera…
Closed-System Solution of the 1D Atom from Collision Model
Maria Maffei, Patrice A. Camati, Alexia Auffèves
Obtaining the total wavefunction evolution of interacting quantum systems provides access to important properties, such as entanglement, shedding light on fundamental aspects, e.g.…
Probing non-classical light fields with energetic witnesses in Waveguide Quantum Electro-Dynamics
Maria Maffei, Patrice A. Camati, Alexia Auffèves
We analyze energy exchanges between a qubit and a resonant field propagating in a waveguide. The joint dynamics is analytically solved within a repeated interaction model. The work…
Alternative experimental ways to access entropy production
Zheng Tan, Patrice A. Camati, Guillaume Coeuret Cauquil +2
We theoretically derive and experimentally compare several different ways to access entropy production in a quantum process under feedback control. We focus on a bipartite quantum…
A two-qubit engine fueled by entangling operations and local measurements
Léa Bresque, Patrice A. Camati, Spencer Rogers +3
We introduce a two-qubit engine that is powered by entangling operations and projective local quantum measurements. Energy is extracted from the detuned qubits coherently exchangin…
Employing Non-Markovian effects to improve the performance of a quantum Otto refrigerator
Patrice A. Camati, Jonas F. G. Santos, Roberto M. Serra
The extension of quantum thermodynamics to situations that go beyond standard thermodynamic settings comprises an important and interesting aspect of its development. One such situ…
Autonomous Maxwell's demon in a cavity QED system
Baldo-Luis Najera-Santos, Patrice A. Camati, Valentin Métillon +4
We present an autonomous Maxwell's demon scheme. It is first analysed theoretically in term of information exchange in a closed system and then implemented experimentally with a si…
Coherence effects in the performance of the quantum Otto heat engine
Patrice A. Camati, Jonas F. G. Santos, Roberto M. Serra
The working substance fueling a quantum heat engine may contain coherence in its energy basis, depending on the dynamics of the engine cycle. In some models of quantum Otto heat en…
Verifying detailed fluctuation relations for discrete feedback-controlled quantum dynamics
Patrice A. Camati, Roberto M. Serra
Discrete quantum feedback control consists of a managed dynamics according to the information acquired by a previous measurement. Energy fluctuations along such dynamics satisfy ge…
Experimental rectification of entropy production by a Maxwell's Demon in a quantum system
P. A. Camati, J. P. S. Peterson, T. B. Batalhão +5
Maxwell's demon explores the role of information in physical processes. Employing information about microscopic degrees of freedom, this "intelligent observer" is capable of compen…
