标题： Experimental realization of scanning quantum microscopy

摘要： 量子成像是一个不断扩展的研究领域，其目标是利用光的量子特性来增强图像重建能力。 尽管已经成功展示了多种量子成像方法，但由于各种物理和技术原因，量子显微镜似乎仍难以应用于实际。 在这里，我们提出了一种成像方法，利用光子对的量子关联和扫描显微镜，实现快速、单模量子成像。 我们首先在金属光栅上测试了该技术，以估计系统的分辨率能力。 此外，我们评估了该技术在全分辨率下可用独立像素数量方面的潜力，与不同的量子成像方法进行比较。 最后，我们展示了洋葱表皮细胞的扫描量子显微镜成像，为可扩展的量子显微镜在生物物理应用中的发展铺平了道路。 我们的结果结合了向中红外波段发展的快速光子对生成和检测技术，可能将量子显微镜的应用扩展到中红外波段，以获取分子指纹区域。 显示英文摘要

摘要： Quantum imaging is an ever expanding research field, in which the aim is to exploit the quantum nature of light to enhance image reconstruction capabilities. Despite a number of successful demonstrations for quantum imaging, quantum microscopy still seems out of the range for practical applications, due to different physical and technical reasons. Here we propose an imaging method exploiting the quantum correlations of photon pairs and a scanning microscope to achieve fast, single mode quantum imaging. We first test our technique on a metal grating to estimate the resolution capabilities of our system. Moreover, we asses its potential in terms of the number of available independent pixels at full resolution compared to different quantum imaging approaches. Finally, we demonstrate scanning quantum microscopy of onion epithelial cells, paving the way towards scalable quantum microscopy for bio-physical applications. Our results, combined with the rapidly evolving photon-pair generation and detection technology towards the mid-infrared, could lead to an extension of quantum microscopy applications towards the mid-infrared, to access the molecular fingerprint region.
