Measurement-Device-Independent Quantum Secret Sharing

Quantum secret sharing plays an important role in quantum communications and secure multiparty computation. In this paper, we present a new measurement-device-independent quantum secret sharing protocol, which can double the space distance between the dealer and each sharer for quantum transmission compared with prior works. Furthermore, it is experimentally feasible with current technology for requiring just three-particle Greenberger-Horne-Zeilinger states and Bell state measurements.
