Published in 2019 at "New Journal of Physics"

DOI: 10.1088/1367-2630/ab573e

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.

Published in 2019 at "Physical Review A"

DOI: 10.1103/physreva.100.026301

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.

Published in 2021 at "Science Advances"

DOI: 10.1126/sciadv.abe0395

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.

Published in 2022 at "Optics express"

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.
