Optical noise correlations and beating the standard quantum limit in advanced gravitational-wave detectors

, 2001
The uncertainty principle, applied naively to the test masses of a laser-interferometer gravitational-wave detector, produces a Standard Quantum Limit (SQL) on the interferometer's sensitivity. It has long been thought that beating this SQL would require

Measuring nanomechanical motion with an imprecision far below the standard quantum limit

, 2010
We demonstrate a transducer of nanomechanical motion based on cavity enhanced optical near-fields capable of achieving a shot-noise limited imprecision more than 10 dB below the standard quantum limit (SQL).
