Bounding the forward classical capacity of bipartite quantum channels

Understand

We introduce various measures of forward classical communication for bipartite quantum channels.

• Since a point-to-point channel is a special case of a bipartite channel, the measures reduce to measures of classical communication for point-to-point channels.
• As it turns out, these reduced measures have been reported in prior work of Wang et al.
• on bounding the classical capacity of a quantum channel.
