"A Quantum Enhanced Gravitational Wave Detector"

Sheila Dwyer , MIT
[Host: Olivier Pfister]
Advanced gravitational wave detectors, currently under construction, are expected to be limited by quantum optical noise in much of their detection band and using squeezed states of light is the most promising way to further improve their sensitivity. I will describe an experiment where squeezed light injection was used to reduce the shot noise limit in a 4 km long interferometric detector of the Laser Interferometer Gravitational-wave Observatory, leading to the best broadband sensitivity achieved to date in a gravitational wave detector.
