我们提出了一个新的方案，以一种简单而优雅的方式研究非最大纠缠态在多方量子态共享中的作用。在我们的方案中，发送者Alice与网络中的个智能体共享个由非最大纠缠态组成的概率信道。我们的协议只涉及贝尔基测量，单量子位测量，和两个量子位的酉变换操作的自由可选代理。我们的方案是一个更方便的实现，因为不需要其他多部联合测量。此外，在我们的方案中，各种概率信道减少了对量子信道的要求，这使得它更实用的物理实现。
We present a new scheme for investigating the usefulness of non-maximally entangled states for multi-party quantum state sharing in a simple and elegant manner. In our scheme, the sender, Alice sharesnvarious probabilistic channels composed of non-maximally entangled states withnagents in a network. Our protocol involves only Bell-basis measurements, single qubit measurements, and a two-qubit unitary transformation operated by free optional agents. Our scheme is a more convenient realization because no other multipartite joint measurements are needed. Furthermore, in our scheme various probabilistic channels lessen the requirement for quantum channels, which makes it more practical for physical implementation.
