我们提出了一个新的应用和实施的庞德锁定技术的询问超导微谐振器。我们讨论了如何通过与稳定的频率源比较，这种技术可以用来表征使用传统方法无法访问的谐振器的属性。具体地说，通过分析噪声谱和Allan偏差，我们获得了有价值的信息的超导平面谐振器中的噪声的性质。与传统方法相比，该技术还大大提高了读出精度和测量吞吐量。[doi：10.1063/1.3648134]
We present a new application and implementation of the Pound-locking technique for the interrogation of superconducting microresonators. We discuss how by comparing against stable frequency sources this technique can be used to characterize properties of resonators that cannot be accessed using traditional methods. Specifically, by analyzing the noise spectra and the Allan deviation, we obtain valuable information about the nature of the noise in superconducting planar resonators. This technique also greatly improves the read-out accuracy and measurement throughput compared to conventional methods. [doi: 10.1063/1.3648134]
