Teleportation of a two-atom entangled state via cavity decay

This paper proposes a scheme for teleporting a two-atom entangledstate using leaky cavities. It uses resonant atom--cavity interactionto map the atomic state onto the cavity field. Then it utilizes theinterference of polarized photons to establish the correlationbetween the distant sender and receiver. The advantage of the schemeis that the fidelity is independent of the cavity decay rate, atomicdecay and detection efficiency.
