摘要

提出了一种新的基于纠缠交换的与多方测量设备无关的量子秘密共享(MDI-QSS)协议。所有的测量任务都委托给不受信任的一方，消除了所有探测器侧信道的漏洞。无论参与者的数量如何，只需要爱因斯坦-波多尔斯基-罗森(EPR)对、单光子和贝尔态测量。与现有的MDI-QSS协议相比，不需要额外的统一操作或格林伯格-霍恩-塞林格(GHZ)状态测量。该协议在实验上是可行的，在实际的多方量子通信网络中具有鼓舞人心的应用潜力。

New multiparty measurement-device-independent quantum secret sharing protocol based on entanglement swapping

A new multiparty measurement-device-independent quantum secret sharing (MDI-QSS) protocol is proposed based on entanglement swapping. All the measurement tasks are delegated to an untrusted party, eliminating all detector-side-channel loopholes. Only Einstein–Podolsky–Rosen (EPR) pairs, single photons and Bell-state measurements are required irrespective of the number of participants. Compared with existing MDI-QSS protocols, no additional unitary operations or Greenberger–Horne–Zeilinger (GHZ)-state measurements are needed. Our protocol is feasible experimentally and holds inspiring potential for the application in practical multiparty quantum communication networks.
