Abstract

Quantum microwave measurement based on Rydberg atoms is a novel microwave measurement technique. To improve its measurement sensitivity over a broadband, this letter presents a mechanically tunable electric field enhancement device, loaded on the the vapor cell. By adjusting the length of the split ring resonator, an electric field enhancement capability of more than 30 dB over a bandwidth of 0.52 GHz to 1.54 GHz is realized in simulation. The experimental results show that its resonance frequency covers from 0.52 GHz to 1.86 GHz with a relative bandwidth of 113%, exhibiting excellent broadband performance. This broadband electric field enhancement device is expected to further improve the performance of quantum microwave measurements.

用于量子微波测量的机械可调谐宽带电场增强谐振器

基于雷德贝格原子的量子微波测量是一种新型微波测量技术。为了提高其宽带测量灵敏度，这封信提出了一种机械可调的电场增强装置，装在蒸发池上。通过调整分裂环谐振器的长度，模拟实现了在 0.52 GHz 至 1.54 GHz 带宽内超过 30 dB 的电场增强能力。实验结果表明，其谐振频率覆盖 0.52 GHz 至 1.86 GHz，相对带宽为 113%，表现出卓越的宽带性能。这种宽带电场增强装置有望进一步提高量子微波测量的性能。
