The Advanced LIGO detector measures the distortion of spacetime from gravitational waves using Michelson interferometers. By injecting a squeezed vacuum state, we have demonstrated shot noise reduction, which enhanced the sensitivity of the LIGO detector. © 2019 The Author(s)

Broadband quantum enhancement of the LIGO detectors with frequency-dependent squeezing

W. Jia, on behalf of LIGO O Detector Author List

We demonstrate the broadband quantum noise reduction of the LIGO detector via injection of frequency-dependent squeezing, which is generated by reflecting squeezed vacuum state from a 300-m detuned filter cavity.
