Teleportation of a two-atom entangled state with a thermal cavity

Abstract

We present a scheme to teleport an unknown atomic entangled state in driven cavity QED. In our scheme, the success probability can reach 1.0. In addition, the scheme is insensitive to the cavity decay and the thermal field.

The Teleportation of an Unknown Quantum State in Ion-Trap Systems

“…From (13), we can see that when ions 1, 3 and ions 2, 6 enter into the cavity, because every ion has two levels, 16 (14), the probability of detecting the state |eeee 1326 is 1/16, the probabilities of successful teleportation in the other fifteen measurement results are easily derived. That is to say, the total success probability is 1/16 × 16 = 1.0.…”

“…In order to overcome the difficulty in teleportation experiments, Zheng [14] and Ye [15] proposed a scheme for teleporting an unknown atomic state in cavity QED without Bell-state measurement, but the probability of success is only 0.25 and 0.5. Jin et al made a proposal for teleporting two-atom state with a probability 1.0 by adding a classical driving field [16].…”

Teleportation of unknown atomic entangled states via Greenberger–Horne–Zeilinger class states

“…However, it is still sensitive to the thermal field. Jin et al [16] propose a scheme to teleport a two-atom entangled state with a thermal cavity. However, a maximally tripartite entangled state is used as quantum channel in the scheme.…”

“…Zheng [19] has proposed a scheme for teleporting an unknown atomic state in cavity QED. Jin et al [20] made a proposal for teleporting two-atom state with a probability 1.0 by adding a classical driving field.…”
