摘要

We suggest a general approach for extending quantum key distribution (QKD) protocols possessing discrete rotational symmetry into quantum secret sharing (QSS) schemes among multiparty, under certain conditions. Only local unitary operations are required for this generalization based on the almost mature technologies of QKD. Theoretically, the number of the participating partners can be arbitrary high. As an application of this method, we propose a fault-tolerant QSS protocol based on a fault-tolerant QKD implementation. The 6-state protocol is also discussed.
