Picturing quantum processes: A first course in quantum theory and diagrammatic reasoning

Abstract

The unique features of the quantum world are explained in this book through the language of diagrams, setting out an innovative visual method for presenting complex theories. Requiring only basic mathematical literacy, this book employs a unique formalism that builds an intuitive understanding of quantum features while eliminating the need for complex calculations. This entirely diagrammatic presentation of quantum theory represents the culmination of ten years of research, uniting classical techniques in linear algebra and Hilbert spaces with cutting-edge developments in quantum computation and foundations. Written in an entertaining and user-friendly style and including more than one hundred exercises, this book is an ideal first course in quantum theory, foundations, and computation for students from undergraduate to PhD level, as well as an opportunity for researchers from a broad range of fields, from physics to biology, linguistics, and cognitive science, to discover a new set of tools for studying processes and interaction. The first book of its kind in the field, the pedagogical focus allows students and researchers to master the techniques of diagrammatic reasoning Heavily illustrated with diagrams and cartoons, the informal style and practical focus opens up the topic of quantum theory to a wider audience Includes over one hundred exercises and worked examples, allowing students to practise the skills they are learning and gain confidence.
