    "abstract": "A scheme for multiparty quantum state sharing of an arbitrary two-particle\nstate is presented with Einstein-Podolsky-Rosen pairs. Any one of the $N$\nagents has the access to regenerate the original state with two local unitary\noperations if he collaborates with the other agents, say the controllers.\nMoreover, each of the controllers is required to take only a product\nmeasurement $\\sigma_x \\otimes \\sigma_x$ on his two particles, which makes this\nscheme more convenient for the agents in the applications on a network than\nothers. As all the quantum source can be used to carry the useful information,\nthe intrinsic efficiency of qubits approaches the maximal value. With a new\nnotation for the multipartite entanglement, the sender need only publish two\nbits of classical information for each measurement, which reduces the\ninformation exchanged largely.",
