Faithfully probabilistic teleportation of an unknown atomic state and cavity field state with a single measurement

This paper shows that, based on the single-photon JC model depicting the resonant interaction of a two-level atomwith a single cavity mode, an unknown atomic state and cavity photon superposition state can be faithfully teleportedwith only a single measurement. The scheme is probabilistic, its success lies on the event that the sender atom (orthe medi-atom, for teleportation of cavity field state) is detected in the higher state. The scheme is in contrast to theprevious ones of using a maximally two- article entangled state as quantum channel.
