    "abstract": "We propose a feasible scheme for teleporting an arbitrary polarization state\nor entanglement of photons by requiring only single-photon (SP) sources, simple\nlinear optical elements and SP quantum non-demolition measurements. An unknown\nSP polarization state can be faithfully teleported either to a duplicate\npolarization state or to an entangled state. Our proposal can be used to\nimplement long-distance quantum communication in a simple way. The scheme is\nwithin the reach of current technology and significantly simplifies the\nrealistc implementation of long-distance high-fidelity quantum communication\nwith photon qubits.",
