论文摘要
我们描述了一种基于用功率检测器注入的光子来测量轴突信号干扰方差的新轴搜索方法。通过将强信号放入微波腔中，不仅获得功率过剩，还可以测量输出功率的方差，可以消除对线性放大器的需求。外部光子对光子转换信号的干扰大大增强了特定轴心频率下的方差，提供了其存在的证据。该方法具有一个优势，即使对于具有较高的深色计数速率的功率检测器，它始终可以在量子噪声限制附近获得灵敏度。我们在分析和数值上描述了该方法的基本概念，并使用简单的演示电路显示了实验结果。
We describe a new axion search method based on measuring the variance in the interference of the axion signal using injected photons with a power detector. The need for a linear amplifier is eliminated by putting a strong signal into the microwave cavity, to acquire not only the power excess but also measure the variance of the output power. The interference of the external photons with the axion to photon converted signal greatly enhances the variance at the particular axion frequency, providing evidence of its existence. This method has an advantage in that it can always obtain sensitivity near the quantum noise limit even for a power detector with high dark count rate. We describe the basic concept of this method both analytically and numerically, and we show experimental results using a simple demonstration circuit.
