The purpose of this book is to provide a deeper insight into the modern theories of molecular matter. It incorporates the most important developments which have taken place during the last decades and reflects the modern trend to abstraction. At the present state of the art we have acquired a fairly good knowledge of "how to. compute" small molecules us ing the methods of quantum chemistry. Yet, in spite of many statements to the contrary and many superficial discussions, the theoretical basis of chemistry and biology is not safely in our hands. It is all but impossible to summarize the modern developments of the theory of matter in nontechnical language. But I hope that I can give some feeling for the problems, the intellectual excitements and the wor ries of some theoreticians. I know very well that such an enterprise is a dangerous adventure and that one says that a clever scientist should take care of his reputation by barricading himself behind the safe wall of his speciality. This volume is not meant to be a textbook; in many respects it has complementary goals. For good and bad reasons, most textbooks ignore the historical and philosophical aspects and go ahead on the basis of crude simplifications; many even lie like the devil and do not shrink from naive indoctrination. Some sections of this book can be read as commentaries on our standard texts, they are intended to stir the waters with controversy.

Quantum State Estimation

Author: Matteo Paris
Publisher: Springer Science & Business Media
ISBN: 3540223290
Release Date: 2004-08-11
Genre: Science

This book is a comprehensive survey of most of the theoretical and experimental achievements in the field of quantum estimation of states and operations. Albeit still quite young, this field has already been recognized as a necessary tool for research in quantum optics and quantum information, beyond being a fascinating subject in its own right since it touches upon the conceptual foundations of quantum mechanics. The book consists of twelve extensive lectures that are essentially self-contained and modular, allowing combination of various chapters as a basis for advanced courses and seminars on theoretical or experimental aspects. The last two chapters, for instance, form a self-contained exposition on quantum discrimination problems. The book will benefit graduate students and newcomers to the field as a high-level but accessible textbook, lecturers in search for advanced course material and researchers wishing to consult a modern and authoritative source of reference.

Handbuch der Laplace Transformation

Release Date: 2013-12-14
Genre: Juvenile Nonfiction

Während der I. Band die theoretischen Grundlagen der Laplace-Transforma tion zum Gegenstand hat, behandelt der vorliegende II. und der nachfolgende III. Band die Anwendungen, wobei es sich natürlich nicht nur um sogenannte «angewandte Mathematik», sondern um die verschiedensten Gebiete der reinen und angewandten Mathematik handelt, in welche die Laplace-Transformation als Hilfsmittel eingreift. Nachdem die Lösung von Funktionalgleichungen vermittels Laplace-Trans formation heutzutage Allgemeingut geworden ist, scheint mir dasjenige An wendungsgebiet, dessen Kenntnis vor allem verbreitet werden sollte, die Theorie der asymptotischen Entwicklungen zu sein. Aus diesem Grund sind diese als I. Teil an die Spitze des II. Bandes gestellt worden. Sowohl in der Theorie als in der Praxis spielen eigentlich die asymptotischen Entwicklungen eine grössere Rolle als die konvergenten Reihen, die den meisten Mathematikern und Inge nieuren aber viel geläufiger sind, weil sie im Unterricht der Hochschulen und in den Lehrbüchern einen erheblich breiteren Raum einnehmen als die asympto tischen Entwicklungen. Um die letzteren mehr in den Vordergrund zu schieben und um die erstaunlichen Möglichkeiten hervorzuheben, die die Laplace-Trans formation gerade auf diesem Gebiet eröffnet, habe ich die aus der ein- und zwei seitigen Laplace-Transformation (oder in anderem Gewand: der Mellin-Transfor mation) sowie aus dem komplexen Umkehrintegral fliessenden asymptotischen Methoden besonders weitgehend ausgearbeitet und durch viele Beispiele illu striert.

Release Date: 2001-06-20
Genre: Mathematics

New ideas on the mathematical foundations of quantum mechanics, related to the theory of quantum measurement, as well as the emergence of quantum optics, quantum electronics and optical communications have shown that the statistical structure of quantum mechanics deserves special investigation. In the meantime it has become a mature subject. In this book, the author, himself a leading researcher in this field, surveys the basic principles and results of the theory, concentrating on mathematically precise formulations. Special attention is given to the measurement dynamics. The presentation is pragmatic, concentrating on the ideas and their motivation. For detailed proofs, the readers, researchers and graduate students, are referred to the extensively documented literature.

Introduction to Photon Communication

Release Date: 2008-09-11
Genre: Technology & Engineering

In recent years, progress in the generation of squeezed states of light, mainly characterized by a reduced noise property, has stimulated important work in relation to their potential use to improve the sensitivity of optical communication systems. These notes are devoted to the detection and information processing of optical signals at very low levels of power. A survey of recent developments from the quantum and classical points of view is presented. Ultimate limits of performance under the criteria of detection and information are established. Some of the results are detailed and may be utilized for the design of practical systems of communication using present technology. The book addresses physicists and engineers interested in present and future developments in optical communications.

Introduction to Quantum State Estimation

Genre: Science

Quantum-state estimation is an important field in quantum information theory that deals with the characterization of states of affairs for quantum sources. This book begins with background formalism in estimation theory to establish the necessary prerequisites. This basic understanding allows us to explore popular likelihood- and entropy-related estimation schemes that are suitable for an introductory survey on the subject. Discussions on practical aspects of quantum-state estimation ensue, with emphasis on the evaluation of tomographic performances for estimation schemes, experimental realizations of quantum measurements and detection of single-mode multi-photon sources. Finally, the concepts of phase-space distribution functions, which compatibly describe these multi-photon sources, are introduced to bridge the gap between discrete and continuous quantum degrees of freedom. This book is intended to serve as an instructive and self-contained medium for advanced undergraduate and postgraduate students to grasp the basics of quantum-state estimation. Any reader with a solid foundation in quantum mechanics, linear algebra and calculus would be able to follow the book comfortably.
