论文摘要
我们提出了一种基于使用CCD摄像头对位移式胶囊状态的直接成像进行挤压光检测的技术。我们表明,只能使用记录的像素到像素到像素的光子波动统计的前两个矩可以准确地估算挤压参数,其准确性可以与标准挤压检测方法(例如平衡的同源物检测)相媲美。最后,我们通过数值模拟摄像机的操作,以低信号采样来重现嘈杂的实验结果,并用高信号采样确认了该理论。
We present a technique for squeezed light detection based on direct imaging of the displaced-squeezed-vacuum state using a CCD camera. We show that the squeezing parameter can be accurately estimated using only the first two moments of the recorded pixel-to-pixel photon fluctuation statistics, with accuracy that rivals that of the standard squeezing detection methods such as a balanced homodyne detection. Finally, we numerically simulate the camera operation, reproducing the noisy experimental results with low signal samplings and confirming the theory with high signal samplings.
