Measurement-device-independent quantum secret sharing with hyper-encoding
文献摘要：
Quantum secret sharing(QSS)is a typical multi-party quantum communication mode,in which the key sender splits a key into several parts and the participants can obtain the key by cooperation.Measurement-device-independent quantum secret sharing(MDI-QSS)is immune to all possible attacks from measurement devices and can greatly enhance QSS's security in practical applications.However,previous MDI-QSS's key generation rate is relatively low.Here,we adopt the polarization-spatial-mode hyper-encoding technology in the MDI-QSS,which can increase single photon's channel capacity.Meanwhile,we use the cross-Kerr nonlinearity to realize the complete hyper-entangled Greenberger-Horne-Zeilinger state analysis.Both above factors can increase MDI-QSS's key generation rate by about 103.The proposed hyper-encoded MDI-QSS protocol may be useful for future multiparity quantum communication applications.
