在分析了目前主要的基于ghz状态的量子秘密共享协议的基础上,提出了直接对量子密钥分布的量子比特进行编码的思想,并在此基础上提出了一种只使用产品状态的量子秘密共享方案。由于目前的量子秘密共享协议中不需要纠缠,特别是不可访问的多纠缠态,因此更适用于秘密共享各方数量较大的情况。理论效率也提高了一倍,接近100%。
After analyzing the main quantum secret sharing protocol based on the GHZ-state, we propose the idea to directly encode the qubit of quantum key distributions, and then present a quantum secret sharing scheme where only product states are employed. As entanglement, especially the inaccessible multi-entangled state, is not necessary in the present quantum secret sharing protocol, it may be more applicable when the number of the parties of secret sharing is large. Its theoretic efficiency is also doubled to approach 100%.
