Gravitational Wave detectors use optical interferometry enhanced with long baseline resonant cavities to achieve the sensitivity required for the recent detections of binary black hole inspirals. Advanced LIGO will soon add squeezed coherent states to enhance sensitivity by quantum mechanics. This talk will detail the detector and why this improvement will initially only improve the inspiral range by ~40%. It will also detail ongoing research on frequency dependent squeezing to allow maximum sensitivity improvements through quantum optics.
