Quantum limit for laser interferometric gravitational wave detectors from optical dissipation
arXiv:1807.11734 · doi:10.1103/PhysRevX.9.011053
Abstract
We derive a quantum limit to the sensitivity of laser interferometric gravitational-wave detectors from optical-loss-induced dissipation, analogous to the sensitivity limit from the mechanical dissipation. It applies universally to different interferometer configurations, and cannot be surpassed unless the optical property is improved. This result provides an answer to the long-standing question of how far we can push the detector sensitivity given the state-of-the-art optics.
