'A masterful and beautifully written exposition of the theoretical ideas and tools of quantum optics that every serious student or researcher, theorist or experimentalist, should have under their belt. Leonhardt tells a connected story, while making each discussion as 'simple as possible, but not simpler'.' Michael G. Raymer, University of Oregon
