Quantum optics In the last decade many important advances have taken place in the field of quantum optics with numerous potential applications. Ideal for graduate courses on quantum optics this textbook provides an up to date account of the basic principles of the subject. Focusing on applications of quantum optics the textbook covers recent developments such as engineering of quantum states quantum optics on a chip nano mechanical mirrors quantum entanglement quantum metrology spin squeezing control of decoherence and many other key topics. Readers are guided through the principles of quantum optics and their uses in a wide variety of areas including quantum information science and quantum mechanics. The textbook features end of chapter exercises with solutions available for instructors at www.cambridge.org 9781107006409. It is invaluable to both graduate students and researchers in physics and photonics quantum information science and quantum communications
