Quantum Thermodynamics

  title={Quantum Thermodynamics},
  author={Sebastian Deffner and Steve Campbell},
  journal={arXiv: Quantum Physics},
This book provides an introduction to the emerging field of quantum thermodynamics, with particular focus on its relation to quantum information and its implications for quantum computers and next generation quantum technologies. [] Key Method Chapter 2 then explores typical thermodynamic settings, such as cycles and work extraction protocols, when the working material is genuinely quantum. Finally, Chapter 3 explores the thermodynamics of quantum information processing and introduces the reader to some more…
Quantum thermodynamics and quantum coherence engines
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,
Quantum thermodynamic devices: From theoretical proposals to experimental reality
Thermodynamics originated in the need to understand novel technologies developed by the Industrial Revolution. However, over the centuries, the description of engines, refrigerators, thermal
Quantum Euler Relation for Local Measurements
A quantum analog of the Euler relation is derived, which is governed by the information retrieved by local quantum measurements, and is demonstrated for the collective dissipation model, where it is found that thermodynamic behavior is exhibited in the weak-coupling regime.
No Entropy Production in Quantum Thermodynamics
In this work we will show that there exists a fundamental difference between microscopic quantum thermodynamics and macroscopic classical thermodynamics. It will be proved that the entropy production
Quantum mechanical work
Regarded as one of the most fundamental concepts of classical mechanics and thermodynamics, work has received well-grounded definitions within the quantum framework since the 1970s, having being
Open-system approach to nonequilibrium quantum thermodynamics at arbitrary coupling
We develop a general theory describing the thermodynamical behavior of open quantum systems coupled to thermal baths beyond perturbation theory. Our approach is based on the exact time-local quantum
Quantum corrections to the entropy in a driven quantum Brownian motion model
The quantum Brownian motion model is a typical model in the study of nonequilibrium quantum thermodynamics. Entropy is one of the most fundamental physical concepts in thermodynamics. In this work,
Strong Coupling Thermodynamics of Open Quantum Systems.
A general thermodynamic framework is presented for open quantum systems in fixed contact with a thermal reservoir. The first and second law are obtained for arbitrary system-reservoir coupling
Experimental characterization of the energetics of quantum logic gates
We characterize the energetic footprint of a two-qubit quantum gate from the perspective of non-equilibrium quantum thermodynamics. We experimentally reconstruct the statistics of energy and entropy
Strong Coupling Quantum Thermodynamics with Renormalized Hamiltonian and Temperature.
We develop the strong coupling quantum thermodynamics based on the solution of the exact master equation. We find that both the Hamiltonian and the temperature must be renormalized due to the


Quantum thermodynamics
Quantum thermodynamics is an emerging research field aiming to extend standard thermodynamics and non-equilibrium statistical physics to ensembles of sizes well below the thermodynamic limit, in
The role of relative entropy in quantum information theory
Quantum mechanics and information theory are among the most important scientific discoveries of the last century. Although these two areas initially developed separately, it has emerged that they are
Quantum heat engine with multilevel quantum systems.
By reformulating the first law of thermodynamics in the fashion of quantum-mechanical operators on the parameter manifold, we propose a universal class of quantum heat engines (QHE) using the
Non-hermitian quantum thermodynamics
It is shown that the Jarzynski equality holds true for all non-hermitian quantum systems with real spectrum, and expresses the second law of thermodynamics for isothermal processes arbitrarily far from equilibrium.

This special issue of Mathematical Structures in Computer Science contains several contributions related to the modern field of Quantum Information and Quantum Computing. The first two papers deal
The Quantum Harmonic Otto Cycle
The quantum Otto cycle serves as a bridge between the macroscopic world of heat engines and the quantum regime of thermal devices composed from a single element, and the dynamical model enables the study of finite time cycles limiting time on the adiabatic and the thermalization times.
Quantum entropy production in phase space
A fluctuation theorem for the nonequilibrium entropy production in quantum phase space is derived, which enables the consistent thermodynamic description of arbitrary quantum systems, open and
Extracting work from a single heat bath via vanishing quantum coherence.
A quantum Carnot engine in which the atoms in the heat bath are given a small bit of quantum coherence and the phase phi, associated with the atomic coherence, provides a new control parameter that can be varied to increase the temperature of the radiation field and to extract work from a single heat bath.
Thermodynamic universality of quantum Carnot engines.
It is shown that the definition of heat has to be modified to account for the thermodynamic cost of maintaining non-Gibbsian equilibrium states and the present study shows that this is not permitted by the laws of thermodynamics-independent of the model.
Entanglement in a Quantum Annealing Processor
Abstract : Entanglement lies at the core of quantum algorithms designed to solve problems that are intractable by classical approaches. One such algorithm, quantum annealing (QA), provides a
