An Introduction to the Formalism of Quantum Information with Continuous Variables

This book is an introduction to quantum information with special emphasis on continuous-variable systems (such as light) that can be described as collections of harmonic oscillators. It covers a selection of basic concepts, focusing on their physical meaning and mathematical treatment. It starts from the very first principles of quantum mechanics, and builds up the concepts and techniques following a logical progression. This is an excellent reference for students with a full semester of standard quantum mechanics and researchers in closely related fields.
