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...

Quantum communication theory is receiving much attention as the basis for practical optical communications and quantum measurements. This book is a unique survey of the activities of the leading research groups from mathematical physics, information theory, and various areas in quantum optics. The contributions deal with both theory and foundations of quantum physics together with technical applications.
