Quantum secret sharing for general access structures based on multiparticle entanglements
In this paper, we study the implementation of quantum secret sharing (QSS) schemes for general access structures rather than the threshold structure. Using multiparticle entanglements in high-dimensional system, three novel multipartite QSS formalisms for general access structures are proposed. The method of how to build general access structures in these formalisms is discussed. A major feature of these formalisms is that a variety of secret sharing schemes with different access structures can be constructed depending on the dealers wish. Besides, hierarchic and threshold authorized structures can also be built. All of which make our formalisms highly flexible.
