基于关联光子对的双缝量子成像实验

摘要

双缝量子成像实验利用参量下转换过程产生的光子之间的关联性，扫描双缝量子成像。通过采集光子符合计数，绘制扫描位置和光子符合计数关联图，在一维方向重现双缝。根据实验采集数据和绘图结果计算双缝缝间距。%Double slit quantum imaging experiment used the correlation of the photon pairs ,w hich generated by PDC ,to scan the double slit quantum imaging .By collecting the photon coincidence number ,drawing the correlation picture of scanning position and photon coincidence number , the double slit in one‐dimension was reconstructed .The distance of the two slit was calculated in the light of the experiment result .
