Description

Quantum noise limits the performance of gravitational-wave (GW) detectors, optomechanical experiments, and even recently proposed dark matter searches. This talk discusses the effort of the Birmingham group towards studies of the quantum noise in these experiments. In particular, we will show how to employ the couple cavity resonance for high GW frequency detectors, heterodyne squeezing technique for the future GW detectors, control of an unstable filter for increasing of the gain-bandwidth product of the LIGO detectors. We will also present an optomechanical and axion search experiments planned in Birmingham which will be limited by quantum noises in optical cavities.
