Abstract:

In this paper, a multi-party quantum secret sharing based on a restricted access structure was designed using the quantum correlation of GHZ entangled state. In this paper, firstly, the participants were divided into two mutually disjoint subsets with three particles of the $d$-dimensional GHZ state as information carriers, and the participants in the two mutually disjoint subsets held the second and third particles of the GHZ state, respectively, and these participants hide their secret shares in quantum states which were acted the unitary transformations.Then, the participants in the subsets recovered the secret with the aid of the classical model. Finally, this scheme is more economical in terms of quantum resources compared to the same type of schemes, and the scheme is simpler and more efficient.
