- A resource- and computationally-efficient protocol for multipartite entanglement distribution in Bell-pair networks (2026) · npj Quantum Information · doi
The protocol is limited to the distribution of GHZ states in arbitrary Bell-pair networks. The protocol does not consider other types of entangled states. The protocol is based on a theoretical model and may not be directly applicable to experimental implementations.

The distribution of entangled states is a key task for quantum networks, but the use of multipartite entangled states comes with its own set of considerations. Prior work has not considered the optimization of cutoff times for quantum conference key agreement protocols.
