Quantum Thermodynamics

An introduction to the thermodynamics of quantum information
Sebastian Deffner, Steve Campbell

Description

Introducing the emerging field of quantum thermodynamics, with a focus on its relation to quantum information and its implications for quantum computers and next-generation quantum technologies, this book is aimed at graduate-level physics students with a working knowledge of quantum mechanics and statistical physics. It provides a brief overview of the development of classical thermodynamics and its quantum formulation, explores typical thermodynamic settings such as cycles and work extraction protocols, and looks at the thermodynamics of quantum information processing, introducing the reader to some more state-of-the-art topics in this exciting and rapidly developing research field.
