Scheme for Entanglement Generation of Two Atoms in Two Bad Cavities

We present a scheme for generation of two-atomic entangled state byusing the interference of polarized photons. The scheme does notrequire complete mapping between the atomic state and the photonicstate, nor does it require the establishment of maximal entanglementbetween the atom and the cavity. And the atom-cavity couplingstrength is smaller than the cavity decay rate. This greatlyrelaxes the requirement on the cavity quality. The scheme is fornon-post-selection results and all the steps of the scheme arewithin the current technologies.
