Realization of the purely spatial Einstein-Podolsky-Rosen paradox in
full-field images of spontaneous parametric down conversion

Paul-Antoine Moreau, Joé Mougin-Sisini, Fabrice Devaux, Eric Lantz
We present a demonstration of EPR entanglement by detecting purely spatial quantum correlations in the near and far-field of highly spatially multimode spontaneous parametric down conversion generated in a type 2 BBO crystal. Full field imaging is performed in the photon counting regime with an electron-multiplying CCD (EMCCD) camera. We obtain a violation of Heisenberg inequalities with inferred quantities taking into account all the biphoton pairs in both the near and far field.
