With one pair of photons’ polarization-entangled state as the quantum channel, we present an explicit generalized linear optical protocol for perfectly teleporting an N-photon Greenberger–Horne–Zeilinger (GHZ) polarization-entangled state from a sender to a receiver using only one two-photon polarization-entangled state as the quantum channel. This protocol has the advantage of transmitting much fewer photons and classical information for teleporting the N-photon GHZ polarization-entangled state than others, and the proposed setup involves simple linear optical elements, photon polarization-entangled states, and conventional photon detectors. These make the present protocol more realizable in experiments.
