Designed for first- and second-year graduate students, and for upper-level undergraduate students who have studied quantum mechanics, the text Introductory Quantum Optics focuses on the quantized electromagnetic field and its effects on atoms. Among the topics covered are quantum phase, coherent states, atom-field interactions, quantization of multimode fields, the quantum coherence theory, the Jaynes-Cummings model, the behavior of nonclassical light, beamsplitters and interferometers, and single-mode field quantitation in a cavity. Some applications of quantum information processing, particularly quantum cryptography, also are explored. Each chapter of the 330-page book includes homework problems and bibliographies.
