Squeezing in Gravitational Wave Detectors

open access: yesGalaxies, 2022
Injecting optical squeezed states of light, a technique known as squeezing, is now a tool for gravitational wave detection. Its ability to reduce quantum noise is helping to reveal more gravitational wave transients, expanding the catalog of observations

Dependence of the detected signal on the kinematic parameters of the satellite in the S-LIGO-E2R space system

open access: yesДоклады Белорусского государственного университета информатики и радиоэлектроники, 2021
The changes of distances less than ~10–21 are registered during the gravitational wave experiment. This feature determines the minimum size of experimental installations and the frequency range of gravitational wave detectors.
