Abstract
Quantum secret sharing has many important applications in quantum communication and secure multiparty computing. In this work, a novel measurement-device-independent protocol for three-party quantum secret sharing is put forward, in which the dealer and two sharers are required to prepare Greenberger-Horne-Zeilinger states and single particles, respectively, but they only need to perform single-particle measurement. As a result, this protocol is feasible in experiments by using current technologies. More importantly, it can extend the spatial distance among three participants for quantum state transmissions at least 15.47% compared to the previous protocols.
