| Abstract: | A scheme for approximately and conditionally teleporting an unknown atomic state via two-photon interaction in cavity QED is proposed. It is the
extension of the scheme of Ref. 11] Phys. Rev. A 69 (2004) 064302],
which is based on Jaynes-Cummings model in QED and where only a time point of
system evolution and the corresponding fidelity implementing the teleportation
are given. In our scheme, the two-photon interaction Jaynes-Cummings model is used to realize the approximate and conditional teleportation. Our scheme does
not involve the Bell-state measurement and an additional atom, only requiring
two atoms and one single-mode cavity. The fidelity of the scheme is higher
than that of Ref. 11]. The scheme may be generalized to not only the
teleportation of the state of a cavity mode to another mode by means of a
single atom but also the teleportation of the state of a trapped ion. |
