[HTML][HTML] Quantum broadcast channels with cooperating decoders: An information-theoretic perspective on quantum repeaters
Communication over a quantum broadcast channel with cooperation between the receivers
is considered. The first form of cooperation addressed is classical conferencing, where
receiver 1 can send classical messages to receiver 2. Another cooperation setting involves
quantum conferencing, where receiver 1 can teleport a quantum state to receiver 2. When
receiver 1 is not required to recover information and its sole purpose is to help the
transmission to receiver 2, the model reduces to the quantum primitive relay channel. The …
