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.

确定性的与测量设备无关的量子秘密共享
多方量子通信可确保在多用户网络之间传输私有信息的信息理论安全性。原则上,独立于测量设备(MDI)的技术可以消除所有检测漏洞,同时通常在基础对账中使用大量量子资源。我们提出了一种三方MDI量子秘密共享(QSS)协议,该协议可抵御所有检测攻击,并且不需要任何基础协调,从而避免了由此产生的相应浪费。所提出的协议允许发送者将专用消息划分为两个部分,并以确定性方式将这些部分发送给不同的接收者。该消息只能通过两个接收方之间的协作来读取。最后,我们讨论了多方QSS协议的广义扩展。
