Squeezing for gravitational wave detection

bowtie

Squeezing at Gravitational Wave signal frequencies (10Hz-10kHz) could be used to reduce quantum noise in Gravitational Wave detectors. In collaboration, the Centre for Gravitational Physics, the ANU Quantum Optics group, the Quantum Measurement Group at MIT and the Hannover University are developing techniques that could be applied to the next generation of optical interferometers designed to detect gravitational waves, such as LIGO.
