Anonymous conference key agreement in linear quantum networks. (arXiv:2205.09169v1 [quant-ph])

Sharing multi-partite quantum entanglement between parties allows for diverse
secure communication tasks to be performed. Among them, conference key
agreement (CKA), an extension of key distribution to multiple parties, has
received much attention recently. Interestingly, CKA can also be performed in a
way that protects the identities of the participating parties, therefore
providing anonymity. In this work, we propose an anonymous CKA protocol for
three parties that is implemented in a highly practical network setting.
Specifically, a line of quantum …
