摘要
虹欧-曼德尔（HOM）效应，又称双光子干涉，在量子信息处理中举足轻重，是我们的相干双光子风探测方法的基础，可实现时频分辨。我们的方法利用了上转换探测器对相位和颜色区别的完全擦除，从而可以观察到独立来源光子之间的 HOM 干涉，而无需延迟调整或主动同步。量子擦除的集成增强了时空和频域的带宽，为高达数十公里/秒的超快连续速度检测铺平了道路。该演示使用的脉冲能量仅为之前水平的 14%，使风力探测范围达到 16 千米，标志着遥感能力的飞跃。
Coherent Two-Photon Atmospheric Lidar Based on Up-Conversion Quantum Erasure
The Hong-Ou-Mandel (HOM) effect, also called two-photon interference, which is pivotal in quantum information processing, serves as the foundation for our coherent two-photon wind detection method, achieving time-frequency discrimination. Our method capitalizes on the complete erasure of phase and color distinctions with up-conversion detectors, allowing for the observation of HOM interference among independently sourced photons without necessitating delay tuning or active synchronization. The integration of quantum erasure enhances the bandwidth in both space-time and frequency domains, paving the way for ultrafast, continuous velocity detection up to tens of km/s. The demonstration uses just 14% pulse energy of previous levels, enabling a wind detection range up to 16 km, marking a quantum leap in remote sensing capabilities.
