我们在场为为以一种简单、漂亮的方式分享的多党的量状态调查 non-maximally 纠缠的状态的实用性的一个新计划。在我们的计划,发送者,各种各样的概率的隧道在一个网络与 n 代理人 non-maximally 纠缠的状态填写了的艾莉斯份额 n。我们的协议包含单一的转变由免费可选的代理人操作了的仅仅钟基础大小,单个 qubit 大小,和 two-qubit。因为没有另外的多国参加的联合大小被需要,我们的计划是一条更方便的认识。而且,在我们的计划,各种各样的概率的隧道为量隧道减少要求,它为物理实现使它更实际。
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 shares n various probabilistic channels composed of non-maximally entangled states with n agents 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 realiza- tion 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.
