Teleportation of a two-atom entangled state using a single EPR pair in cavity QED
Xin Ji, Ke Li, Zhang Shou · Chinese Physics · 2006
We propose a scheme for teleporting a two-atom entangled state in cavity quantum electrodynamics (QED). In the scheme, we choose a single Einstein–Podolsky–Rosen (EPR) pair as the quantum channel which is shared by the sender and the receiver. By using the atom–cavity-field interaction and introducing an additional atom, we can teleport the two-atom entangled state successfully with a probability of 1.0. Moreover, we show that the scheme is insensitive to cavity decay and thermal field.
