Broadband reduction of quantum radiation pressure noise via squeezed light injection
The Heisenberg uncertainty principle states that the position of an object cannot be known with infinite precision, as the momentum of the object would then be totally uncertain. This momentum uncertainty then leads to position uncertainty in future measurements. When continuously measuring the position of an object, this quantum effect, known as back-action, limits the achievable precision1,2 . In audio-band, interferometer-type gravitational-wave detectors, this backaction effect...[Show more]
