Abstract

We consider recent schemes [J.M. Liu, B. Weng, Physica A 367 (2006) 215] to teleport unknown atomic states and superposition of zero- and two-photon states using the two-photon Jaynes–Cummings model. Here we do the same using the “full two-photon Jaynes–Cumming”, valid for arbitrary average number of photons. The success probability and fidelity of this teleportation are also considered.
