Recently,several proof of principle experiments have demonstrated the advantages of quantum technologies over classical *** present challenge is to surpass the limits of proof of principle demonstrations to approach real *** letter presents such an achievement in the field of quantum enhanced *** particular,we describe the realization of a sub-shot-noise wide field microscope based on spatially multi-mode non-classical photon number correlations in twin *** microscope produces realtime images of 8000 pixels at full resolution,for a 500μm2 field of view,with noise reduced to 80%of the shot noise level(for each pixel),which is suitable for absorption imaging of complex *** fast post-elaboration,specifically applying a quantum enhanced median filter,the noise can be further reduced(to o30%of the shot noise level)by setting a trade-off with the resolution,thus achieving the best sensitivity per incident photon reported in absorption microscopy.
