Summary
Equipment and instrumentation for breaking the quantum measurement barrier. This equipment will support Australia's partnership in the international effort to detect gravitational waves, which would allow the first direct observation of black holes and mark the beginning of exploration of the gravitational wave spectrum.
Quantum enhancement of long baseline gravitational wave detectors. This project will design and construct a quantum optical system which when used in future long baseline gravitational wave detectors will enhance sensitivity across their detection frequency band, from 10 Hz to 10 kHz. This project will use this system on small scale optical sensors to prove the concept. In so doing, it will use squeezing to reduce quantum radiation pressure noise for the first time. This system will then be read ....Quantum enhancement of long baseline gravitational wave detectors. This project will design and construct a quantum optical system which when used in future long baseline gravitational wave detectors will enhance sensitivity across their detection frequency band, from 10 Hz to 10 kHz. This project will use this system on small scale optical sensors to prove the concept. In so doing, it will use squeezing to reduce quantum radiation pressure noise for the first time. This system will then be ready for deployment on an early upgrade of Advanced LIGO increasing the science output of this detector, turning gravitational wave detection into gravitational wave astronomy.Read moreRead less
Quantum enhancement of gravitational wave astronomy. The project aims to design, build and test a long wavelength ‘squeezed vacuum’ source reducing quantum noise by more than a factor of 10 across the audio frequency band with long term stability and reliability. This quantum technology is one of three key areas of improvement planned for the gravitational wave detector, LIGO Voyager. The project will enhance the sensitivity and the reach of gravitational wave astronomy and cosmology, and improv ....Quantum enhancement of gravitational wave astronomy.

This quantum technology is one of three key areas of improvement planned for the gravitational wave detector, LIGO Voyager. The project will enhance the sensitivity and the reach of gravitational wave astronomy and cosmology, and improve the fidelity and reach of gravitational wave observations. Technologies developed may find application in other areas of precision measurements and gravitational wave observations .Read moreRead less
Instrumentation for the era of gravitational wave science. This project aims to study noise sources that limit the low-frequency performance of gravitational wave antenna: thermal noise, quantum radiation pressure noise and Newtonian noise. Gravitational wave detection is a new way in which to observe our universe. Although detectors such as advanced LIGO (Laser Interferometer Gravitational-Wave Observatory) should detect gravitational waves, further sensitivity improvement, particularly at low ....Instrumentation for the era of gravitational wave science. This project aims to study noise sources that limit the low-frequency performance of gravitational wave antenna: thermal noise, quantum radiation pressure noise and Newtonian noise. Gravitational wave detection is a new way in which to observe our universe. Although detectors such as advanced LIGO (Laser Interferometer Gravitational-Wave Observatory) should detect gravitational waves, further sensitivity improvement, particularly at low frequencies, will be needed to provide event rates necessary for astronomy. Expected project outcomes will support the development of the first free mass interferometer to operate at 120K using silicon optics, a vital facility for the world community. Pushing the boundaries of measurement may also drive innovation in optical sensing with potential applications in defence, security and exploration.Read moreRead less
