This book is a self-contained guide to the world of quantum optical processes which addresses different aspects relevant in quantum optics and quantum information. The basic descriptions, measurement techniques, possible sources, nonclassical features, practical implications and applications of the quantization of light and its interaction with matter, are explored. The observed quantum properties such as coherent superposition, entanglement, nonlocality, decoherence and no-cloning, are discussed. The quantum optical processes such as continuous variable entanglement swapping, teleportation and telecloning from which follow the practical aspects such as quantum gate operations, cryptography and error correction are considered. In turn, the advantages and inherent challenges including the foresight in implementing continuous variable quantum communication and computation protocols are highlighted. The author gives a concise background with corresponding applications, the necessary mathematical derivation, simplified examples, illustrations and demonstrations, and the relative interpretations and outlooks.

This book is intended to serve a multi-disciplinary readership, namely the atomic physics and quantum optics communities who seek to extend their research to applications, especially, to the field of quantum information processing as well as the theoretical quantum information community who builds up research on physically realizable systems such as optical setups and various atomic schemes. The content of this book also attracts other communities such as photonics who seeks to link research with continuous variable quantum information processing.

Autorentext

Sintayehu Tesfa is assistant professor at Jazan University where he teaches general physics courses and adjunct professor at Adama and Addis Ababa Universities where he advises students and teaches quantum optics. Earlier, he taught quantum optics at Dilla University and he has been a guest scientist at Max Planck Institute of complex systems, Dresden. Since last 15 years, he has been working on quantum optics and quantum information with emphasis to exploring nonclassical properties of light. Particularly, he is one of the pioneers in the study of the quantification of the degree of quantum entanglement and discord of the light generated by nonlinear and linear optical sources such as parametric up-conversion and correlated emission laser.
