Efficiently Computable Limits on EPR Pair Generation in Quantum Broadcast Channels
Patrick Hayden, Debbie Leung, Hjalmar Rall +1
We investigate the generation of EPR pairs between three observers in a general causally structured setting, where communication occurs via a noisy quantum broadcast channel. The m…

Three-Receiver Quantum Broadcast Channels: Classical Communication with Quantum Non-unique Decoding
Farzin Salek, Patrick Hayden, Masahito Hayashi
In network communication, it is common in broadcasting scenarios for there to exist a hierarchy among receivers based on information they decode due, for example, to different phys…
