摘要: 为提高效率,提出了一种直接共享经典信息的量子秘密共享协议。协议利用Pauli矩阵的特殊性质将经典信息编码在Bell态上实现秘密共享,为了检测是否存在窃听者,通过随机插入诱骗光子的方法确保传输的安全。分析表明该协议是安全的,效率可以达到1个Be11态共享2 bit经典信息。

Abstract: To improve the efficiency, the quantum secret sharing scheme sharing classic information directly is proposed. The scheme makes full use of the special properties of Pauli matrix and encodes the information in the Bell states to achieve secret sharing. For detection of eavesdropping, it inserts the random decoy photons to ensure secure transmission in the scheme. The protocol is secure and one Bell state can be used to share two bits information.
Key words: quantum secret sharing, Pauli matrix, Bell states, decoy photons
