Wei Wang · Jisuanji gongcheng yu sheji · 2010
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.
