论文摘要
半Quantum秘密共享（SQSS）是半Quantum加密术的重要分支，与量子秘密共享（QSS）不同，并非所有各方都具有量子能力。所有以前的SQSS协议都有三个共同的特征：（1）它们采用产品状态或纠缠状态作为初始量子资源； （2）量子聚会制备的颗粒以树型的方式传输； （3）他们要求经典各方具有测量能力。在本文中，提出了两个带有单个颗粒的圆形SQSS协议，其中第一个要求经典各方具有测量能力，而第二个则没有该要求。与以前的SQSS协议相比，所提出的SQSS协议具有一些不同的特征：（1）它们采用单个粒子而不是产品状态或纠缠状态作为初始量子资源； （2）量子聚会制备的颗粒以圆形方式传输； （3）第二个协议从测量能力中释放经典各方。拟议的SQSS协议对窃听者的一些著名攻击非常强大，例如量度呈现攻击，截距呈现攻击和纠缠量的攻击，并且实际上具有当前的量子技术。
Semi-quantum secret sharing (SQSS) is an important branch of semi-quantum cryptography, and differs from quantum secret sharing (QSS) in that not all parties are required to possess quantum capabilities. All previous SQSS protocols have three common features: (1) they adopt product states or entangled states as initial quantum resource; (2) the particles prepared by quantum party are transmitted in a tree-type way; and (3) they require the classical parties to possess the measurement capability. In this paper, two circular SQSS protocols with single particles are suggested, where the first one requires the classical parties to possess the measurement capability while the second one does not have this requirement. Compared with the previous SQSS protocols, the proposed SQSS protocols have some distinct features: (1) they adopt single particles rather than product states or entangled states as initial quantum resource; (2) the particles prepared by quantum party are transmitted in a circular way; and (3) the second protocol releases the classical parties from the measurement capability. The proposed SQSS protocols are robust against some famous attacks from an eavesdropper, such as the measure-resend attack, the intercept-resend attack and the entangle-measure attack, and are feasible with present quantum technologies in reality.
