Beschreibung
For the first time, this book assembles in a single volume accounts
of many phenomena involving quantum interference in optical fields
and atomic systems. It provides detailed theoretical treatments and
experimental analyses of such phenomena as quantum erasure, quantum
lithography, multi-atom entanglement, quantum beats, control of
decoherence, phase control of quantum interference, coherent
population trapping, electromagnetically induced transparency and
absorption, lasing without inversion, subluminal and superluminal
light propagation, storage of photons, quantum interference in phase
space, interference and diffraction of cold atoms, and interference
between Bose-Einstein condensates. This book fills a gap in the
literature and will be useful to both experimentalists and theoreticians.
The ?eld that encompasses the term “quantum interference” combines a number of separate concepts, and has a variety of manifestations in d- ferent areas of physics. In the sense considered here, quantum interference is concerned with coherence and correlation phenomena in radiation ?elds and between their sources. It is intimately connected with the phenomenon of non-separability (or entanglement) in quantum mechanics. On account of this, it is obvious that quantum interference may be regarded as a com- nent of quantum information theory, which investigates the ability of the electromagnetic ?eld to transfer information between correlated (entangled) systems. Since it is important to transfer information with the minimum of corruption, the theory of quantum interference is naturally related to the theory of quantum ?uctuations and decoherence. Since the early days of quantum mechanics, interference has been - scribed as the real quantum mystery. Feynman, in his famous introduction to the lectures on the single particle superposition principle, referred in the following way to the phenomenon of interference: “it has in it the heart of quantum mechanics”, and it is really ‘the only mystery’ of quantum mech- ics. With the development of experimental techniques, it has been possible to carry out many of the early Gedanken experiments that played an important role in developing our understanding of the fundamentals of quantum int- ference and entanglement. Despite its long history, quantum interference still challenges our understanding, and continues to excite our imagination.
