Quantum thermodynamics

open access: yesSciPost Physics Lecture Notes
The theory of quantum thermodynamics investigates how the concepts of heat, work, and temperature can be carried over to the quantum realm, where fluctuations and randomness are fundamentally unavoidable.

Perspective on quantum thermodynamics

open access: yesNew Journal of Physics, 2016
Classical thermodynamics is unrivalled in its range of applications and relevance to everyday life. It enables a description of complex systems, made up of microscopic particles, in terms of a small number of macroscopic quantities, such as work and ...

Thermodynamic Implementations of Quantum Processes [PDF]

open access: yesCommunications in Mathematical Physics, 2021
AbstractRecent understanding of the thermodynamics of small-scale systems have enabled the characterization of the thermodynamic requirements of implementing quantum processes for fixed input states. Here, we extend these results to construct optimal universal implementations of a given process, that is, implementations that are accurate for any ...

Thermodynamics of Quantum Trajectories on a Quantum Computer

open access: yesPhysical Review Letters, 2023
Quantum computers have recently become available as noisy intermediate-scale quantum devices. Already these machines yield a useful environment for research on quantum systems and dynamics. Building on this opportunity, we investigate open-system dynamics that are simulated on a quantum computer by coupling a system of interest to an ancilla.

Thermodynamics of a quantum annealer [PDF]

open access: yesQuantum Science and Technology, 2020
Abstract The D-wave processor is a partially controllable open quantum system that exchanges energy with its surrounding environment (in the form of heat) and with the external time dependent control fields (in the form of work). Despite being rarely thought as such, it is a thermodynamic machine. Here we investigate the properties of

Quantum thermodynamics and quantum coherence engines [PDF]

open access: yesTURKISH JOURNAL OF PHYSICS, 2020
Advantages of quantum effects in several technologies, such as computation and communication, have already been well appreciated, and some devices, such as quantum computers and communication links, exhibiting superiority to their classical counterparts have been demonstrated.

Can Quantum Correlations Lead to Violation of the Second Law of Thermodynamics?

open access: yesEntropy, 2021
Quantum entanglement can cause the efficiency of a heat engine to be greater than the efficiency of the Carnot cycle. However, this does not mean a violation of the second law of thermodynamics, since there is no local equilibrium for pure quantum states,

Thermodynamics of Quantum Causal Models: An Inclusive, Hamiltonian Approach [PDF]

open access: yesQuantum, 2020
Operational quantum stochastic thermodynamics is a recently proposed theory to study the thermodynamics of open systems based on the rigorous notion of a quantum stochastic process or quantum causal model.
