Gravitational wave detectors opened a new window to the universe by measuring the ripples in spacetime produced by colliding black holes and neutron stars, but they are ultimately limited by quantum fluctuations induced by light reflecting off of mirrors. Researchers have conducted a new experiment to explore a way to cancel this quantum backaction and improve detector sensitivity.
