Surpassing the repeaterless bound with a photon-number encoded measurement-device-independent quantum key distribution protocol
Abstract Decoherence is detrimental to quantum key distribution (QKD) over large distances. One of the proposed solutions is to use quantum repeaters, which divide the total distance between the users into smaller segments to minimise the effects of the losses in the channel. Here we introduce a mea...
