提出了一种基于多维GHZ态的高效量子秘密共享方案。交易商对特殊维数粒子GHZ状态进行特殊的幺正运算来编码秘密，并利用两种非正交基的可分辨性来保护秘密，但参与者可以通过测量任一基上的状态来获得秘密。因此，每个粒子都可以用来携带秘密信息，粒子的利用率远远高于BB84协议。此外，与传统的二维粒子相比，多维粒子可以带来更多的信息。与现有基于BB84协议的方案相比，我们的方案在实际应用中具有更高的效率。
An efficient quantum secret sharing scheme based on multi-dimensional GHZ state is proposed. The dealer performs the special unitary operation on the specialn-dimensionaln-particle GHZ state to encode the secret, and uses the distinguishability of two nonorthogonal basis to protect the secret, but the participants can get the secret through measuring the state in either basis. So every particle can be used to bring secret information, and the utilization ratio of the particles is much higher than the BB84 protocol. Besides, the multi-dimensional particle can bring more information than the traditional 2-dimensional particle. Compared to the existing schemes based on the BB84 protocol, our scheme will be more efficient in practice.
