Abstract--We study a protocol in which many parties use
quantum communication to transfer a shared state to a receiver
without communicating with each other. This protocol is a
multiparty version of the fully quantum Slepian-Wolf protocol
for two senders and arises through the repeated application of the
two-sender protocol. We describe bounds on the achievable rate
region for the distributed compression problem. The inner bound
arises by expressing the achievable rate region for our protocol
in terms of its vertices and extreme rays and, equivalently, in
terms of facet inequalities. We also prove an outer bound on all
possible rates for distributed compression based on multiparty
squashed entanglement.
