An efficient and secure multiparty quantum secret sharing scheme based on single photons

摘要

A scheme of multiparty quantum secret sharing of classical messages (QSSCM) is proposed based on single photons and local unitary operations. In this scheme, eavesdropping checks are performed only twice, and one photon can generate one bit of classical secret message except those chosen for eavesdropping check; in addition, only the sender and one of the agents are required to store photons. Thus, this scheme is more practical and efficient.
