Query: Atomic entanglement purification using photonic Faraday rotation   We describe an entanglement purification protocol (EPP) for atomic entangled
pair using photonic Faraday rotation. It is shown that after the two single
photons input-output process in cavity QED, the high quality entangled atomic
state can be obtained from the low quality mixed entangled atomic states.
Different from other EPPs, the two pairs of mixed states do not need to intact
directly. As the photonic Faraday rotation works on the low-Q cavities, this
EPP is useful in both quantum communication and computation.
