Approximate teleportation of an unknown atomic state in the two-photon Jaynes–Cummings model

A scheme is proposed for approximately teleporting an unknown atomic state by using the two-photon Jaynes–Cummings model. Only two atoms and one cavity are needed to achieve the teleportation scheme. This scheme can be applied to teleporting the superposition of zero- and two-photon states from one cavity mode to another cavity mode with only one atom.
