This textbook provides comprehensive coverage of the fundamentals of integrated quantum photonics (IQP) and its key applications.  While there are books available in the fields of quantum, integrated, and nonlinear optics, there is no single book which provides extensive coverage of the fundamentals in a unified context for understanding the field of IQP and its applicability in emerging research and industrial areas. Based on the author’s classroom-tested lecture courses and tutorials delivered around the world, the book has a pedagogical approach with concepts derived from basic principles, and enhanced with exercises to hone both the reader’s fundamental understanding and ability to apply the core concepts. As IQP is expected to play a significant role in the future of quantum information science and technology, this book will provide a much needed source of fundamental and practical knowledge for the novice or advanced reader alike. This textbook is ideal for a taught course in integrated quantum photonics at the upper undergraduate or beginning graduate level. It can also be used as a reference for more seasoned researchers and as a self-study resource for industry researchers looking to upgrade their skills and knowledge.
