| contents | In this work, we prove security of a quantum conference key agreement (QCKA) protocol augmented with a classical advantage distillation (CAD) protocol. We derive a proof of security, in the finite key setting, that is able to bound the secure key rate for any general, coherent, attack. We evaluate the performance of the system, showing our result can improve the noise tolerance of the protocol in some, but not all, scenarios. |
