Abstract

The quantum nature of light imposes a fundamental limit on the sensitivity of ground based gravitational wave detectors. Squeezed states of light, produced via parametric downconversion in a non linear medium, have recently been employed to beat the quantum limit and extend the astrophysical reach of the most sensitive gravitational wave detector ever built.
