Beschreibung
The new technological prospects of processing quantum infor- mation are attracting not only physicists but also re- searchers from other communities, most prominently computer scientists. This book provides a self-contained introduction to the basic theoretical concepts, experimental techniques and recent advances in the fields of quantum communication, quantum information and quantum computation. In accordance with their interdisciplinary character, these central research topics in the emerging area of quantum technology are addressed both from the physical point of view and from the point of view of computer science, by leading experts. The introductory and self-contained character of the contributions should make this book particularly attractive to students and active researchers in physics and computer science who want to become acquainted with the underlying basic ideas and recent advances in the rapidly evolving field of quantum information processing.
Though quantum theory is celebrating its 100th anniversary this year, quan tum information processing is still a remarkably young research field. The questions driving this research field reflect a profound change in the gen eral attitude towards the fundamental aspects of quantum theory. So far, research on the foundations of quantum theory has been concerned mainly with the theoretical exploration of those particular features which distin guish quantum theory from classical physics. The main intention of quantum information p~ocessing is to exploit these specific features for technological purposes. As early as 1935, Erwin SchrSdinger had already noted that one of these characteristic features of quantum theory is the phenomenon of entan glement. Many years passed from this early insight until John Bell realized the quantitative consequences of the corresponding quantum correlations in his famous work from 1964. These theoretical predictions inspired numerous experiments, which all support the peculiar features predicted for quantum correlations. From these purely theoretical insights, it again required a long period of development to arrive at those potentially useful applications which are now of central interest for the processing of quantum information. The following contributions provide an introductory overview of basic problems, methods and topical results in this research field. The idea of pro ducing this volume was born at a symposium on this subject which was held at the 1999 annual spring meeting of the Deutsche Physikalische Gesellschaff in Heidelberg.
