标题： Two-Photon Airy Disk

摘要： 我们报告了使用纠缠双光子源对量子艾里盘衍射图样的实验观察。 与之前在远场极限下观察到亚波长衍射图样的量子光刻实验不同，我们使用凸透镜进行了夫琅禾费衍射实验。 实验结果表明，双光子艾里盘具有超分辨率光斑，其分辨率超过了经典衍射极限。 特别是，光斑尺寸可以通过焦距进行良好控制，这适用于光学超聚焦。 我们的实验可以促进量子光刻的潜在应用。 显示英文摘要

摘要： We report an experimental observation of quantum Airy disk diffraction pattern using an entangled two-photon source. In contrast to the previous quantum lithography experiments where the subwavelength diffraction patterns were observed in the far field limit, we perform the Fraunhofer diffraction experiment with a convex lens. The experimental result shows that the two-photon Airy disk is provided with the super-resolution spot, which surpasses the classical diffraction limit. In particular, the spot size can be well controlled by the focal length, which adapted to optical super-focusing. Our experiment can promote potential application of quantum lithography.
