Abstract: | We propose a scheme for approximately and conditionally teleporting an unknown atomic-entangled state in dissipative cavity QED. It
is the further development of the scheme of Phys. Rev. A 69
(2004) 064302], where the cavity mode decay has not been considered and the
state teleportated is an unknown atomic state. In this paper, we investigate
the influence of the decay on the approximate and conditional teleportation of the unknown atomic-entangled state, which is different from that teleportated
in Phys. Rev. A 69 (2004) 064302] and then give the fidelity of
the teleportation, which depends on the cavity mode decay. The scheme
may be generalized to not only the teleportation of the
cavity-mode-entangled-state by means of a single atom but also the
teleportation of the unknown trapped-ion-entangled-state in a linear ion trap. |
