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… read more here.

Abstract: Device-independent quantum key distribution (DI-QKD) enables two remote parties to share an information-theoretically secure key without any assumptions on the inner workings of the devices used. Device-independent conference key agreement (DI-CKA) is multipartite DI-QKD in… read more here.

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… read more here.

Abstract: Quantum networks aim to enable quantum information tasks among multiple parties. Quantum conference key agreement (QCKA) is a typical task in quantum networks, which distributes information-theoretically secure keys among multiple users. However, QCKA relying on… read more here.

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… read more here.

DOI: 10.1364/oe.460725
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… read more here.
