Deterministic measurement-device-independent quantum secret sharing

作者：ZiKai Gao,Tao Li,ZhenHua Li

摘要：Multiparty quantum communication ensures information-theoretic security for transmitting private information among multiuser networks.In principle,measurement-device-independent(MDI)techniques can close all detection loopholes while usually utilizing large amounts of quantum resources in basis reconciliation.We propose a three-party MDI quantum secret sharing(QSS)protocol that is secure against all detection attacks and does not require any basis reconciliation,avoiding the corresponding waste arising from it.The proposed protocol allows a sender to divide a private message into two parts and send those parts to different receivers in a deterministic way.The message can only be read through cooperation between the two receivers.Finally,we discuss the generalized extension of a multiparty QSS protocol.
