'Elements of Quantum Information' introduces the reader to the fascinating field of quantum information processing, which lives on the interface between computer science, physics, mathematics, and engineering. This interdisciplinary branch of science thrives on the use of quantum mechanics as a resource for high potential modern applications. With its wide coverage of experiments, applications, and specialized topics - all written by renowned experts - 'Elements of Quantum Information' provides an indispensable up-to-date account of the state of the art of this rapidly advancing field and takes the reader straight up to the frontiers of current research. The articles have first appeared as a special issue of the journal 'Fortschritte der Physik/Progress of Physics'. Since then, they have been carefully updated. The book will be an inspiring source of information and insight for anyone researching and specializing in experiments and theory of quantum information.

This book offers a concise introduction to quantum optics through the lens of phase space, blending modern style with effective pedagogy. It equips students for research with detailed derivations, numerous illustrations, and a variety of problems at the end of each chapter. The theoretical discussions are often paired with corresponding experimental insights, and a comprehensive reference list guides further exploration of the literature. It also serves as a valuable reference for advanced researchers. The author begins with a thorough review of defining experiments in quantum optics and a brief overview of quantum mechanics, using the Wigner phase space distribution function to illustrate quantum state properties. The connection between semi-classical phase space and the Berry phase is explored through WKB wave descriptions, providing insights into wave packet dynamics, fractional revivals, and the Talbot effect. The first half focuses on mechanical oscillators, while the second half delves into the quantization of the radiation field, covering topics like optical interferometry, atom-field interactions, quantum state preparation and measurement, entanglement, decoherence, and atom optics in quantized light fields. This text presents quantum optics in a clear manner, offering extensive references for students to engage with contemporary scientific literature, making it a valuable resource for students, educators, and research
