This book aims to provide support for lecture courses on general quantum physics for university undergraduates in the final year(s) of a physics degree programme. The first chapter reviews the basic quantum mechanics needed for getting the best out of the text. Instructors are then free to concentrate on a group of chapters, or select components from all chapters, whichever suits their needs. The text covers key themes of quantum physics, taking the perspective achieved after more than a century of research, and emphasizes the effectiveness and the subtlety of quantum concepts in explaining diverse physical phenomena. The book helps bring out these unifying ideas and illustrates them with important examples from modern experiments and applications. The book maintains a level of presentation accessible to undergraduates, and provides exercises and solutions to reinforce the learning process. Solutions to the exercises are available via the OUP webpage link for the book.
