Engineering distant cavity fields entanglement through Bragg diffraction of neutral atoms

We propose various schemes for the generation of cavity field entangled states including Bell states, W‐state and GHZ states. The fundamental ingredient of all such engineering schematics is a simple, state of the art cavity field off-resonant, first order Bragg diffraction of the neutral two-level atoms. The proposal can be extended to generate any arbitrarily large multipartite state forming a quantum web. The proposal is comparatively decoherence resistant and is quite experimentally feasible with high enough success probability and fidelity under prevailing cavity QED research scenario.
