Abstract
The Laser Interferometer Gravitational Wave Observatory (LIGO) has been directly detecting gravitational waves from compact binary mergers since 2015. We report on the first use of squeezed vacuum states in the direct measurement of gravitational waves with the Advanced LIGO H1 and L1 detectors. This achievement is the culmination of decades of research to implement squeezed states in gravitational-wave detectors. During the ongoing O3 observation run, squeezed states are improving the sensitivity of the LIGO interferometers to signals above 50 Hz by up to 3 dB, thereby increasing the expected detection rate by 40% (H1) and 50% (L1).

[25] The BNS range corresponds to the radius of the sensitive volume of the Universe for 1.4 – 1.4 M ⊙ neutron star binary systems (assuming a detection threshold with matched-filter signal-to-noise ratio of 8 in a single detector), integrated over the interferometer antenna pattern, and averaged over all binary inclinations and orientations. Although BNS signals end above a kHz and typical BBH signals end around 500 Hz, both types of signals accumulate most of their SNR in the 30–300 Hz band. Thus the impact of squeezing on detector range is similar for both BNS and BBH. [26] 26 H. Yu (to be published). [27] 27 S. S. Y. Chua , Classical Quantum Gravity 31 , 035017 ( 2014 ).
