On Quantum Capacity and its Bound

Quantum Physics 2007-05-23 v1

Abstract

The quantum capacity of a pure quantum channel and that of classical-quantum-classical channel are discussed in detail based on the fully quantum mechanical mutual entropy. It is proved that the quantum capacity generalizes the so-called Holevo bound.
