Abstract: The intense research activity on Twin-Field (TF) quantum key distribution (QKD) is motivated by the fact that two users can establish a secret key by relying on single-photon interference in an untrusted node. Thanks to…

Abstract: In this manuscript we discuss the device-independent conference key agreement (DICKA) protocol [Phys. Rev. A 97, 022307 (2018)]. We show that the suggested honest implementation fails, because perfect correlated measurement results and the required Bell-inequality…

Abstract: When Alice and Bob invite their friends, quantum key distribution with multiparty entanglement enables secure conference call. Quantum networks will provide multinode entanglement enabling secure communication on a global scale. Traditional quantum communication protocols consume…

Abstract: Twin-field interference-based quantum conference key agreement protocols have been proposed and have achieved good performance in terms of the key rate and transmission distance in the finite-key regime. However, its performance significantly decreases when the…
