ISIT 2026, IEEE International Symposium on Information Theory, 28 June - 3 July 2026, Guangzhou, China
We undertake a Shannon theoretic study of the problem of communicating over a 3−user classical quantum broadcast channel (3−CQBC) and focus on characterizing inner
bounds. Adopting the technique of tilting, smoothing, and augmentation discovered by Sen [1], [2] and combining it with our coset code strategy, we derive a new inner bound to the capacity region of a 3−CQBC. The derived inner bound subsumes all current known bounds and is proven to be strictly larger for identified examples.
