    "abstract": "We study the quantum limits in an optomechanical sensor based on a detuned\nhigh-finesse cavity with a movable mirror. We show that the radiation pressure\nexerted on the mirror by the light in the detuned cavity induces a modification\nof the mirror dynamics and makes the mirror motion sensitive to the signal.\nThis leads to an amplification of the signal by the mirror dynamics, and to an\nimprovement of the sensor sensitivity beyond the standard quantum limit, up to\nan ultimate quantum limit only related to the mechanical dissipation of the\nmirror. This improvement is somewhat similar to the one predicted in detuned\nsignal-recycled gravitational-waves interferometers, and makes a high-finesse\ncavity a model system to test these quantum effects",
