光学系统的空间分辨率受衍射的限制。通过采用扫描源/探测器配置或物体的双光子响应，提出了各种方案来实现分辨率增强。在这里，我们通过实验证明了一种基于空间量子相关双光子质心估计的全场分辨率增强方案。我们的标准量子限制方案能够使用低能量和低强度的红外照明(即与
The spatial resolution of an optical system is limited by diffraction. Various schemes have been proposed to achieve resolution enhancement by employing either a scanning source/detector configuration or a two-photon response of the object. Here, we experimentally demonstrate a full-field resolution-enhancing scheme, based on the centroid estimation of spatially quantum-correlated biphotons. Our standard-quantum-limited scheme is able to image a general non-fluorescing object, using low-energy and low-intensity infrared illumination (i.e., with
