Abstract:In this paper, we propose a new scheme to enhance the performance of the Gussian-modulated coherent state(GMCS) continuous-variable measurement-device-independent quantum key distribution(CV-MDI-QKD) system via quantum scissors(QS) operation at Bob’s side. As an non-deterministic amplifying setup, we firstly introduce the QS-enhanced CV-MDI-QKD protocol and then investigate the success probability of the QS operation in accordance with the equivalent one-way scheme. Afterwards, we investigate the effect of the… Show more
