摘要

双光子频率梳在很大程度上由于其与电信基础设施的兼容性而成为量子网络的有前途的资源。在这项工作中，我们提出了一种利用时变线性腔周期性地将宽带频率纠缠光子压缩成双光子频率梳的方法。我们的方法依赖于输入腔耦合的快速调制，在每个输出梳状线中产生与窄带滤波器相似的高光谱纯度，但没有相关的通量损失。我们研究了光谱纯度和压缩对耦合强度、空腔损耗和开关速度的依赖，找到了支持纯度超过0.999和峰值增强因子超过100倍的现实机制。

From broadband biphotons to frequency combs via spectral compression with time-varying cavities.

Biphoton frequency combs are promising resources for quantum networking due in large part to their compatibility with the telecommunication infrastructure. In this work, we propose a method to periodically compress broadband frequency-entangled photons into biphoton frequency combs by utilizing time-varying linear cavities. Our approach hinges on rapid modulation of the input cavity coupling, yielding high spectral purity in each output comb line similar to that achieved with narrowband filters, but without the associated loss in flux. We examine the dependence of spectral purity and compression on coupling strength, cavity loss, and switching speed, finding realistic regimes supporting purities in excess of 0.999 and peak enhancement factors of 100× and beyond.
