A passionate and personal account of the early days of quantum information and quantum computing, this unique book is a collection of more than 500 letters between the author and many of the founders of these intriguing fields. Christopher A. Fuchs is one of the most penetrating modern thinkers on the philosophical foundations of quantum mechanics. This remarkable book follows his journey as he comes to grips with the quantum world. It contains correspondence with Charles Bennett, Gilles Brassard, Rolf Landauer, N. David Mermin, Michael Nielsen, Asher Peres, John Preskill, Abner Shimony, William Wootters, Anton Zeilinger, and many others. Filled with diary entries, anecdotes, historical selections, and research ideas, this book will fascinate physicists, philosophers, and historians of science.

Related to the key areas of Pauli's and Jung's joint interests, the book covers overlapping issues from the perspectives of physics, philosophy, and psychology. Of primary significance are epistemological questions connected to issues such as realism, measurement, observation, consciousness, and the unconscious. The contributions assess the extensive material that we have about Pauli's and Jung's ideas today, with particular respect to concrete research questions and projects based on and related to current knowledge.
