The Holevo-Schumacher-Westmoreland Channel Capacity for a Class of Qudit Unital Channels
John A. Cortese
The Holevo-Schumacher-Westmoreland (HSW) classical (entanglement-unassisted) channel capacity for a class of qudit unital channels is shown to be C = log2(d) - Smin, where d is the…

Relative Entropy and Single Qubit Holevo-Schumacher-Westmoreland Channel Capacity
John Cortese
The relative entropy description of Holevo-Schumacher-Westmoreland (HSW) classical channel capacity is applied to single qubit channels. A simple formula for the relative entropy o…
