Abstract
Classically, the spatial resolution of the image of an object is usually determined by the Rayleigh criterion. However, quantum properties of light have been exploited to form images with resolutions exceeding this criterion and beating the standard quantum limit, which allow high measurement sensitivity. We found that it is possible to super-resolve a distributed object made of two parts that are spatially separated but when superposed over each other form an object. A coincidence interference pattern of a nonlocal two-photon system with periodicity proportional to $\ensuremath{\lambda}/2$ was measured even when each photon, with wavelength of $\ensuremath{\lambda}$, has been scattered by different parts of an object, none of them being the object itself.
