摘要
具有高频率分辨率的超宽带射频信号实时感知具有挑战性，其受限于电子模数转换器的采样率和数字信号处理能力。通过将量子力学与压缩感知相结合，提出了量子压缩感知用于宽带射频信号频率测量。利用电光晶体作为传感器，用待测信号调制相干光子的波函数。通过具有低时间抖动单光子探测器和时间数字转换器检测被调制的稀疏光子，可恢复频谱。演示了超过 50 GHz 的实时分析带宽，并具有傅里叶变换极限分辨率。进一步的仿真表明，利用现有技术可将其扩展至超过 300 GHz。

The data in this paper is not correct, we need to replace the data, but we need time to redo the experiment. We have to withdraw the paper now, and upload the article after we got right data
