    "abstract": "We present a scheme for symmetric multiparty quantum state sharing of an\narbitrary $m$-qubit state with $m$ Greenberger-Horne-Zeilinger states following\nsome ideas from the controlled teleportation [Phys. Rev. A \\textbf{72}, 02338\n(2005)]. The sender Alice performs $m$ Bell-state measurements on her $2m$\nparticles and the controllers need only to take some single-photon product\nmeasurements on their photons independently, not Bell-state measurements, which\nmakes this scheme more convenient than the latter. Also it does not require the\nparties to perform a controlled-NOT gate on the photons for reconstructing the\nunknown $m$-qubit state and it is an optimal one as its efficiency for qubits\napproaches the maximal value.",
