Universal superposition codes: capacity regions of compound quantum broadcast channel with confidential messages

open access: yes, 2020
We derive universal codes for transmission of broadcast and confidential messages over classical-quantum-quantum and fully quantum channels. These codes are robust to channel uncertainties considered in the compound model.
