标题： Position-correlated biphoton wavefront sensing for quantum adaptive imaging

摘要： 量子成像使用空间纠缠光子具有增强的空间分辨率、对噪声的鲁棒性以及反直觉现象等优势。 在量子自适应光学中，通过使用经典光束检测像差源或在光源不可达时对双光子扫描校正相位，实现了双光子空间像差校正。 在这里，介绍了一种名为位置相关双光子 Shack-Hartmann 波前传感的新方法，其中在具有强位置相关的光子对上添加的相位图案是通过微透镜阵列的后焦平面上的光子位置质心分布重建的。 实验上，展示了双光子相位测量和对抗塑料薄膜干扰的自适应成像。 这种单次测量方法是一种更直接和高效的双光子相位测量方法，适用于集成到量子显微镜、远程成像和通信中。 显示英文摘要

摘要： Quantum imaging with spatially entangled photons offers advantages such as enhanced spatial resolution, robustness against noise, and counter-intuitive phenomena. In quantum adaptive optics, biphoton spatial aberration correction has been achieved by using classical beams to detect the aberration source or scanning the correction phase on biphotons when the source is unreachable. Here, a new method named position-correlated biphoton Shack-Hartmann wavefront sensing is introduced, where the phase pattern added on photon pairs with a strong position correlation is reconstructed from their position centroid distribution at the back focal plane of a microlens array. Experimentally, biphoton phase measurement and adaptive imaging against the disturbance of a plastic film are demonstrated. This single-shot method is a more direct and efficient approach to biphoton phase measurement, suitable for integration into quantum microscopy, remote imaging, and communication.
