A novel quantum secret sharing (QSS) protocol is suggested by utilizing the evolution law of atom via cavity quantum electrodynamics (QED) in this paper. It employs two-atom product states rather than entangled states as the initial quantum resource, and adopts single-atom measurements rather than two-atom or multiple-atom joint measurements. It needs neither the unitary operations nor the quantum entanglement swapping. It can resist both the outside attack and the participant attack.

通过 Cavity QED 共享量子秘密

本文利用原子的演化规律通过腔量子电动力学（QED）提出了一种新的量子秘密共享（QSS）协议。它采用双原子积态而不是纠缠态作为初始量子资源，采用单原子测量而不是双原子或多原子联合测量。它既不需要酉运算也不需要量子纠缠交换。它既可以抵抗外部攻击，也可以抵抗参与者攻击。
