ON CAPACITIES OF QUANTUM CHANNELS

Masanori Ohya
Dénes Petz
Noboru Watanabe

Abstract: Capacities of quantum mechanical channels are defined in terms of mutual information quantities. Geometry of the relative entropy is used to express capacity as a divergence radius. The symmetric quantum spin 1/2 channel and the attenuation channel of Boson fields are discussed as examples.
