This detailed, yet accessible introduction to the exciting field of quantum decoherence guides the reader through the basics and then explains the essential consequences of the phenomenon for our understanding of the world. Among other things, the book examines how the classical world of our experience can emerge from quantum mechanics, and reviews the implications of decoherence for the various interpretations of quantum mechanics. The author also reviews recent experiments confirming the puzzling consequences of the quantum superposition principle ("Schrödinger kittens") and making decoherence processes directly observable. The book includes an introduction to quantum computing and the role of decoherence and a discussion of quantum mechanics and the brain.

Unique in its wide range of the covered material, this book emphasizes foundational implications without neglecting detailed descriptions of experiments and applications Includes supplementary material: sn.pub/extras

Autorentext

Maximilian Schlosshauer is an internationally recognized researcher in the foundations of quantum mechanics in general and in quantum decoherence in particular. After completing his undergraduate education at Freiburg University, Germany, he graduated from Lund University, Sweden, with a Master of Science degree in 2001. He received a Ph.D. degree in Physics from the University of Washington in Seattle in 2005. His postgraduate research (with Arthur Fine) was focused on decoherence and the quantum-to-classical transition. He is currently an Australian Research Council Postdoctoral Fellow in the Department of Physics at the University of Melbourne, Australia. Besides his interest in decoherence and the foundations of quantum mechanics, he has also contributed important research in theoretical biophysics.

Klappentext
The ultimate introduction, textbook, and reference on decoherence and the quantum-to-classical transition. This detailed but accessible text describes the concepts, formalism, interpretation, and experimental observation of decoherence and explains how decoherence is responsible for the emergence, from the realm of quantum mechanics, of the classical world of our experience. Topics include: • Foundational problems at the quantumclassical border; • The role of the environment and entanglement; • Environment-induced loss of coherence and superselection; • Scattering-induced decoherence and spatial localization; • Master equations; • Decoherence models; • Experimental realization of "Schrödinger kittens" and their decoherence; • Quantum computing, quantum error correction, and decoherence-free subspaces; • Implications of decoherence for interpretations of quantum mechanics and for the "measurement problem"; • Decoherence in the brain. Written in a lucid and concise style that is accessible to all readers with a basic knowledge of quantum mechanics, this stimulating book tells the "classical from quantum" story in a comprehensive and coherent manner that brings together the foundational, technical, and experimental aspects of decoherence. It will be an indispensable resource for newcomers and experts alike. "Reads like a bestseller. An engaging and intuitive treatment of a very important subject, combining the scope of a monograph with the clarity of a textbook and the intellectual excitement of a Sherlock Holmes adventure." Wojciech Zurek, Los Alamos "Everyone who works in the borderlands between quantum and classical physics, from philosophers of physics to quantum-computer technologists, will find much here to stimulate andinspire." Gerard Milburn, University of Queensland "A thorough, readable, and very useful account of decoherence theory and its diverse applications. Valuable as a text and as a reference work, both for graduate students and for active researchers in the field." Steve Adler, IAS, Princeton
