摘　　要：为进一步提高量子秘密共享协议的效率和安全性,结合量子Grove搜索算法提出一种基于极化单光子的量子秘密共享协议。效率分析结果表明,该方案可以将全部量子态用于密钥共享,理论效率为100%。在方案的安全性证明中,借助量子Grove算子和量子纠缠特性得出方案能够有效抵抗中间人攻击,同时该方案利用辅助量子态进行监视,能够以高概率检测特洛伊木马攻击。通过对Grove算子进行高维推广,证明了方案推广到(,)的可行性和实用性。To improve the efficiency and security of quantum secret sharing,with the help of Grover’s algorithm,a quantum secret sharing scheme based on polarized single photons is proposed.Efficiency analysis indicates that all qubits can be used in the secret sharing and its theoretical efficiency achieves to 100%.In the security proving,with Grover’s operator and quantum entanglement,the protocol can resist the middleman attack effectively.And by using auxiliary qubit,the protocol can detect the Trojan horse attack with high probability.The extension of Grover’s operator shows the scheme which contains pairs is feasible and applicable.Finally,a view concerning the future work in quantum secret sharing is represented.
