量子噪声对像LIGO这样的干涉引力波探测器的灵敏度施加了根本限制，表现为散粒噪声和量子辐射压力噪声。在这里，我们提出了第一个实现的全尺度引力波探测器中的频率相关的压缩，从而减少散粒噪声和量子辐射压力噪声，与宽带探测器增强从几十赫兹到几千赫兹。在LIGO Hanford探测器中，在1 kHz附近，压缩使探测器噪声幅度降低了1.6倍（4.0 dB）;在利文斯顿探测器中，噪声降低了1.9倍（5.8 dB）。这些改进直接影响了LIGO对高频源的科学输出（例如，双星中子星星合并后物理学）。低频灵敏度的提高，使探测器的探测范围在没有挤压的情况下提高了15% - 18%，相当于天体物理探测率提高了65%。作为LIGO A+升级的一部分，通过在每个探测器上添加一个300米长的滤波腔来实现频率相关的挤压。
Quantum noise imposes a fundamental limitation on the sensitivity of interferometric gravitational-wave detectors like LIGO, manifesting as shot noise and quantum radiation pressure noise. Here, we present the first realization of frequency-dependent squeezing in full-scale gravitational-wave detectors, resulting in the reduction of both shot noise and quantum radiation pressure noise, with broadband detector enhancement from tens of hertz to several kilohertz. In the LIGO Hanford detector, squeezing reduced the detector noise amplitude by a factor of 1.6 (4.0 dB) near 1 kHz; in the Livingston detector, the noise reduction was a factor of 1.9 (5.8 dB). These improvements directly impact LIGO ’ s scientific output for high-frequency sources (e.g., binary neutron star postmerger physics). The improved low-frequency sensitivity, which boosted the detector range by 15% – 18% with respect to no squeezing, corresponds to an increase in the astrophysical detection rate of up to 65%. Frequency-dependent squeezing was enabled by the addition of a 300-meter-long filter cavity to each detector as part of the LIGO A þ upgrade.
