Universal Classical-Quantum Superposition Coding and Universal Classical-Quantum Multiple Access Channel Coding

We derive universal classical-quantum superposition coding and multiple access channel by using generalized packing lemmas for the type method. Using our code, we establish capacity region of a compound broadcast with degraded message sets. Our codes have two types codes. One is code joint decoding other separate decoding. It not so easy to construct former that universally achieves general points beyond corner points. First, latter region. Then, converting coder, above desired type.
