我们已经在实验上演示了利用自发参数下转换源产生的纠缠光子和使用单像素探测器在单光子水平上进行高分辨率压缩鬼影成像。对于给定的均方误差，重建二维图像所需的光子数比使用光栅扫描的量子幽灵成像实验中的光子数要少得多。这一过程不仅缩短了数据采集时间，还提出了一种更经济地使用光子来形成微光和量子图像的方法。
We have experimentally demonstrated high-resolution compressive ghost imaging at the single-photon level using entangled photons produced by a spontaneous parametric down-conversion source and using single-pixel detectors. For a given mean-squared error, the number of photons needed to reconstruct a two-dimensional image is found to be much smaller than that in quantum ghost imaging experiments employing a raster scan. This procedure not only shortens the data acquisition time, but also suggests a more economical use of photons for low-light-level and quantum image formation.
