Generation of two-mode entanglement between separated cavities

We propose a scheme for the generation of two-mode entangled states between two spatially separated cavities. It utilizes a two-level atom sequentially coupling to two high-Q cavities with strong classical driving fields. By suitably choosing the intensities and detunings of the fields and precisely controlling the dynamics, entangled coherent states and Bell states can be produced between the modes of the two cavities. These entangled states should have applications in quantum information processing.
