title: Entanglement in atomic resonance fluorescence.
abstract: The resonance fluorescence from regular atomic systems is shown to represent a continuous source of non-gaussian entangled radiation propagating in two different directions. For a single atom entanglement occurs under the same conditions as squeezing. For more atoms, the entanglement can be more robust against dephasing than squeezing, hence providing a useful continuous source for various applications of entangled radiation.
