论文摘要
单光子 - 阿瓦兰奇二极管（SPAD）阵列是生物探测器，光学范围和传感和量子光学器件的必需工具。但是，到目前为止，它们的少量像素，低量子效率和少量填充因子阻碍了它们用于实际成像应用的使用。在这里，我们使用100 kpixels spad摄像头展示了全场纠缠的光子对相关成像。通过测量超过5亿对位置之间的光子重合，我们可以检索成像系统的全点扩展功能，并随后通过空间纠缠的光子对照明的目标对象的高分辨率图像。我们表明，我们的成像方法是对杂散光的鲁棒性，使量子成像技术能够超越实验室实验，向现实世界中的应用（例如量子激光雷达）进行。
Single-photon-avalanche diode (SPAD) arrays are essential tools in biophotonics, optical ranging and sensing and quantum optics. However, their small number of pixels, low quantum efficiency and small fill factor have so far hindered their use for practical imaging applications. Here, we demonstrate full-field entangled photon pair correlation imaging using a 100-kpixels SPAD camera. By measuring photon coincidences between more than 500 million pairs of positions, we retrieve the full point spread function of the imaging system and subsequently high-resolution images of target objects illuminated by spatially entangled photon pairs. We show that our imaging approach is robust against stray light, enabling quantum imaging technologies to move beyond laboratory experiments towards real-world applications such as quantum LiDAR.
