Abstract: The optimal coordination rates are determined in three primary settings of multi-user quantum networks, thus characterizing the minimal resources required in order to simulate a joint quantum state among multiple parties. We study the following models: (1) a cascade network with rate-limited entanglement, (2) a broadcast network, which consists of a single sender and two receivers, (3) a multiple-access network with two senders and a single receiver. We establish the necessary and sufficient conditions on the asymptotically-achievable communication and entanglement rates in each setting. At last, we show the implications of our results on nonlocal games with quantum strategies.

Coordination Capacity for Classical-Quantum Correlations [16.025002076222002]
Network coordination is considered in three basic settings. We consider the simulation of a classical-quantum state between two nodes with rate-limited common randomness (CR) and communication. At last, we consider a broadcast setting, where a sender and two receivers simulate a classical-quantum-quantum state using rate-limited CR and communication.

Entangled Pair Resource Allocation under Uncertain Fidelity Requirements [59.83361663430336]
In quantum networks, effective entanglement routing facilitates communication between quantum source and quantum destination nodes. We propose a resource allocation model for entangled pairs and an entanglement routing model with a fidelity guarantee. Our proposed model can reduce the total cost by at least 20% compared to the baseline model.

Experimental multi-state quantum discrimination through a Quantum network [63.1241529629348]
We have experimentally implemented two discrimination schemes in a minimum-error scenario based on a receiver featured by a network structure and a dynamical processing of information. The first protocol achieves binary optimal discrimination, while the second one provides a novel approach to multi-state quantum discrimination, relying on the dynamical features of the network-like receiver.
