Entanglement in atomic resonance fluorescence
arXiv:1001.2448 · doi:10.1103/PhysRevLett.104.233602
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.
