Aspects of multistation quantum information broadcasting

Abstract
We study quantum information transmission over multiparty quantum channel. In particular, we show an equivalence of different capacity notions and provide a multiletter characterization of a capacity region for a general quantum channel with senders and receivers. We point out natural generalizations to the case of two-way classical communication capacity.
