Quantum key distribution (QKD) is used to establish secret keys between users for secure communication. To execute the QKD protocol and establish a key for end users over long distance, entanglements need to be routed over a quantum network to the end users. Routing in quantum networks for QKD has been explored for pairwise keys, however the multiparty case is still an open problem.

In this work, we develop routing algorithms for multiparty QKD. Both single and multipath algorithms are developed and simulated for fixed and dynamic routing scenarios.

Our routing protocols result in significantly higher key rates when compared to fixed path routing schemes. We demonstrate that multiparty quantum key distribution outperforms pairwise quantum key distribution in a simulated network setting. Additionally, we derive analytical expressions for the 3-party case.
