Abstract

We present the first experimental prototype of a stable phase-insensitive optomechanical quantum filter designed to enhance the shot-noise-limited sensitivity of interferometers, such as gravitational-wave detectors and axion detectors, without use of squeezed light. Our prototype features a high-Q silicon nitride membrane that is dispersively coupled to a system of two coupled optical cavities with a total length of approximately 6 meters, making it the first meter-scale system optomechanically coupled to a nano-object and operating in the resolved sideband regime. We report on the latest results and discuss other potential applications of our prototype, including optomechanical cooling below the ground-state level, quantum non-demolition measurements of the quantum states of the membrane, and strong coherent coupling of two nano-objects separated by a distance of several meters.
