Abstract
The entanglement properties of two beams of light can reside in subtle correlations that exist in the unavoidable quantum fluctuations of the amplitudes and the phases of the electric fields. Recent advances in the generation of nonclassical light with 4-wave mixing in an atomic vapor have permitted the production and the observation of entanglement which is localized in almost arbitrary transverse regions of a pair of beams. These multi-spatial-mode entangled beams may prove useful for an array of applications ranging from noise-free imaging and improved position sensing to quantum information processing.Citation
