Decoherence

Produktbeschreibung

Over the course of the past decade, decoherence has become a ubiquitous scienti?c term popular in all kinds of research, from fundamental theories of quantum physics to applications in nanoengineering. Decoherence has been hailed as the solution to long-standing foundational problems dating back to the beginnings of quantum mechanics. It has been cursed as the key obstacle to next-generation technologies, such as quantum computers (another se- ingly omnipresent ?eld of research). And while decoherence has been directly observed in various experiments, its scope and meaning have often been m- understood and misrepresented. Decoherence makes a fantastic subject of research, as it touches upon many di?erent facets of physics, from phi- sophically inclined questions of interpretation all the way to down-to-earth problems in experimental settings and engineering applications. This book will introduce the reader, in an accessible and self-contained manner, to these various fascinating aspects of decoherence. It will focus in particularontherelationofdecoherencetotheso-calledquantum-to-classical transition, i. e. , the question of how decoherence may explain the emergence of the classical appearance of the macroscopic world around us from the underlying quantum substrate. Thescopeofthisbookisrelativelybroadinordertofamiliarizethereader withthemanyfacetsofdecoherence,inboththetheoreticalandexperimental domains. Throughout the book, I have sought to maintain a healthy balance betweentheconceptualideasassociatedwiththedecoherenceprogramonthe one hand and the formal and mathematical details on the other hand. This book will establish a proper understanding of decoherence as a pure quantum phenomenon and will emphasize the importance of the correct interpretation of theconsequences and achievements of decoherence.

Kritik

From the reviews:

"A thorough and readable representation of today's understanding of the topic ... An excellent overview of the various theoretical approaches to the physics that leads to decoherence. A particular strength is that it includes accounts of several experiments demonstrating the decoherence mechanism in detail ... An important resource for anyone interested in decoherence. It is very well written and it will contribute to further conceptual and theoretical development and to new experiments."

Review by Anton Zeilinger, published in Nature 451, 18 (2008)

"An excellent monograph about what the best current thoughts are on the link between quantum and classical physics. ... rewarding reading for physicists who do not have the time or the mathematical preparation to delve into all the details. For such readers, the book includes interesting and accessible discussions of recent experiments ... . a welcome contribution. The index is well organized to help readers find their way around. And the more than 500 up-to-date references are a bonus for the more interested, persistent reader." (Eugen Merzbacher, Physics Today, September, 2008)



"A very fine tour of the decoherence program in all its facets. ... Schlosshauer's book is highly recommended. ... [He] has written an excellent survey of a field that is of the greatest possible interest for the foundations of quantum physics." (N. P. Landsman, Studies in History and Philosophy of Modern Physics, Vol. 40, 2009) 

Autoreninfo

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.
