Quantum Zero-Error Capacity and HSW Capacity
AIP Conference Proceedings, 2004We give in this paper a formal proof that the zero‐error capacity of a noisy quantum channel is less than or equal to the Holevo‐Schumacher‐Westmoreland capacity.

We discuss in this chapter the following topics in quantum information: (1) the channel capacity for quantum communication processes by applying the quantum mutual entropy introduced in Chap. 7, (2) formulations of quantum analogues of McMillan’s theorem and coding type theorem for entanglement transmission.

The pure quantum entanglement is generalized to the case of mixed compoundstates to include the classical-quantum encoding as a particular case. The mutual information of the entangled states leads to a different type of entropy which doubles the von Neumann entropy for a given state and is the true quantum entropy.
