    "abstract": "After analysing the main quantum secret sharing protocol based on the\nentanglement states, we propose an idea to directly encode the qubit of quantum\nkey distributions, and then present a quantum secret sharing scheme where only\nproduct states are employed. As entanglement, especially the inaccessable\nmulti-entangled state, is not necessary in the present quantum secret sharing\nprotocol, it may be more applicable when the number of the parties of secret\nsharing is large. Its theoretic efficiency is also doubled to approach 100%.",
