One-shot Classical-Quantum Multiple Access Wiretap Channel with Common Message

In this paper, the classical-quantum multiple access wiretap channel with a common message is studied under the one-shot settings. In this regard, inner bound is achieved using simultaneous decoding. One important problem in multi-terminal quantum networks is the nonexistence of a proved simultaneous decoder for decoding more than two messages simultaneously. The main focus of this paper is to construct a simultaneous decoder for one-shot settings.
