Owing to the disadvantages of low communication efficiency, high measuring complexity and implementation difficulties in the existing quantum state sharing protocols, an efficient and simple three-party deterministic quantum state sharing protocol based on Bell states is proposed. During the procession of the protocol, only Bell-state measurements is used and the communication efficiency is improved obviously, hence, the proposed protocol is easily realized in physical experiment and its successful probabilities be all 100%. On the other hand, the protocol is generalized from three parties to multiple parties, and the feasibility of the scheme is illustrated by taking the four-party quantum state sharing as an example.

基于贝尔状态的两量子比特量子状态共享协议

针对现有量子状态共享协议通信效率低、测量复杂度高、实现困难等缺点，提出了一种高效简单的基于贝尔态的三方确定性量子状态共享协议。该协议在处理过程中仅采用贝尔状态测量，通信效率明显提高，因此，该协议在物理实验中很容易实现，成功概率均为100%。另一方面，将协议从三方推广到多方，以四方量子状态共享为例说明该方案的可行性。
