physical systems, but rather a new framework with universal applicability. This book shows

how we can reconstruct the theory from six information-theoretical principles, by rebuilding

the quantum rules from the bottom up. Step by step, the reader will learn how to master the

counterintuitive aspects of the quantum world, and how to efficiently reconstruct quantum

information protocols from first principles. Using intuitive graphical notation to represent

equations, and with shorter and more efficient derivations, the theory can be understood

and assimilated with exceptional ease. Offering a radically new perspective on the field, the

book contains an efficient course of quantum theory and quantum information for

undergraduates. It is aimed at researchers, professionals, and students in physics, computer

science and philosophy, as well as the curious outsider seeking a deeper understanding of

the theory.

Reviews

**Nicolas Gisin (Université de Genève):**

*“An extraordinary book on the deep principles behind quantum theory.”*

**Scott Aaronson (University of Texas at Austin):**

*“Part quantum mechanics textbook, part original research contribution, this book is a fascinating, audacious effort to “rebuild quantum mechanics from the ground up’, presenting it as the logical consequence of simple information-theoretic postulates. Students wishing to learn quantum information should read it and do all the exercises!”*

**Valerio Scarani (National University of Singapore):**

*“I can hardly think of a more consciously, carefully crafted itinerary into these matters. After all, there are only a handful of trusted guides along these paths, and here you are in very safe hands.”*

**Alex Wilce (Susquehanna University):**

*"A delightful, inspiring, and persuasive introduction to their way of looking at finite-dimensional quantum theory."*
