Main description: Nach einer physikalischen Betrachtung der Quantenmechanik werden zunächst die benötigten mathematischen Grundlagen eingeführt bzw. wiederholt: Vektorräume, darauf aufbauend Hilberträume und die Tensorrechnung, gefolgt von den Grundlagen der Wahrscheinlichkeitsr…
"Quantum physics allows entirely new forms of computation and cryptography, which could perform tasks currently impossible on classical devices, leading to an explosion of new algorithms, communications protocols, and suggestions for physical implementations of all these ideas. …
"This book is devoted to quantum computing, a new, multidisciplinary research area crossing quantum mechanics, theoretical computer science and mathematics. It contains an introduction to quantum computing as well as the most important recent results on the topic. Two famous alg…

Explains how quantum theory developed to make quantum computers work in practice as well as in principle. He takes us beyond the arena of theoretical physics to explore their practical applications -- from machines which learn through "intuition" and trial and error to unhackabl…
Main description: The main emphasis of this work is the mathematical theory of quantum channels and their entropic and information characteristics. The past years were marked with impressive progress made by several researchers in solution of some difficult problems, in particul…
