Quantum Information Theory - an Invitation

Abstract

We give a non-technical introduction of the basic concepts of Quantum Information Theory along the distinction between possible and impossible machines. We then proceed to describe the mathematical framework of Quantum Information Theory. The capacities of a quantum channel for classical and for quantum information are defined in a unified scheme, and a mathematical characterization of all teleportation and dense coding schemes is given.

51 pages, 12 Figures, LaTeX+dvips. Will appear in a volume "Quantum information - an introduction to basic theoretical concepts and experiments" in Springer Tracts in Modern Physics
