Reviews

"It is time to present quantum theory in a different way in the light of all the recent work in Quantum Information. Rau has thought this through in great detail. The content is road-tested, and looks compelling. " - Lucien Hardy, Perimeter Institute, Waterloo

"Fills an important gap in the market, and could be used in a variety of departments (such as computer science) as a first introduction to quantum theory." - Philip Goyal, University of Albany

"An amazing book, introducing both the underlying physics and the math in a beautifully comprehensive way." - Bart Selman, Cornell University
