A Quantum Secret Sharing Scheme Based on Polarized Single Photons and Quantum Computation

结合量子计算算子提出一种基于极化单光子的量子秘密共享协议。该方案可以将全部量子态用于密钥共享,借助量子置换算子和量子纠缠特性证明了方案能够有效抵抗中间人攻击,利用辅助量子态进行监视,方案能够以高概率检测特洛伊木马攻击。通过对置换算子进行高维推广,证明了方案推广到(n,n)的可行性和实用性。

With the help of quantum computation operator,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.With the permutation operator and quantum entanglement,the protocol can resist the middleman attack effectively.By using the auxiliary qubit,the protocol can detect the Trojan horse attack with high probability.The extension of the permutation operator shows the scheme which contains n pairs is feasible and applicable.
