'Picturing Quantum Processes is a lively and refreshing romp through the authors diagrammatic and categorical approach to quantum processes. I recommend this book with no lower age limit required!' Louis Kauffman, University of Illinois 'This book develops from scratch the category theoretic, and diagrammatic, language for quantum theory, especially quantum processes. It is a remarkable achievement: vigorous, crystal-clear, complete - ... Read moreand a delight to read.' Jeremy Butterfield, University of Cambridge 'The book employs a unique formalism developed by the authors, which allows a more intuitive understanding of quantum features and eliminates complex calculations. As a result, knowledge of advanced mathematics is not required. ... An informal and entertaining style is adopted, which makes this book easily approachable by students at their first encounter with quantum theory. That said, it will probably appeal more to Ph.D. students and researchers who are already familiar with the subject and are interested in looking at different treatment of this matter. The text is also accompanied by a rich set of exercises.'
