This book provides a solid pedagogical background in the techniques used in quantum optics, with an emphasis on open quantum systems. Suitable for undergraduates as a second semester quantum mechanics course or first year graduate students, this book begins with a short summary of quantum mechanics and contains physics of open systems and their application to light/matter interactions. Written in a simplified manner and classroom tested, this book provides the fundamentals of quantum optics and includes recent developments in the field.

Key Features:

• Solid introduction to the key features of the field
• Excellent first exposure to nonequilibrium quantum statistical mechanics
• Developed from 30 years of teaching
• Includes recent developments in the field
• Second edition includes 4 new chapters
