| Long-distance device-independent conference key agreement | QCRYPT 2024 | Makoto Ishihara, Wojciech Roga, Jonatan Bohr Brask, Ulrik Lund Andersen, Masahiro Takeoka |
We propose a long-distance device-independent conference key agreement (DI-CKA) protocol. We use an efficient GHZ state distribution protocol based on entanglement swapping. We calculate a key rate of our protocol from violation of a multipartite Bell inequality and show that our protocol can distribute a secret key over longer distance than a direct transmission DI-CKA protocol. We also consider practical displacement-based measurement and show experimental feasibility of our protocol. |
