Laser threshold sensing. This project aims to create a new class of room-temperature ultra-sensitive magnetometers based on laser threshold magnetometry. By using nitrogen-vacancy colour centres in diamond, these magnetometers will demonstrate at least femto-Tesla per root Hertz sensitivity, and could replace SQUID magnetometers.

Unconditional photonic entanglement verification and quantum metrology using fast, ultra-high-efficiency photon detectors. Scientists can currently only give in-principle demonstrations of the powerful advantages offered by the quantum physics of photons – particles of light. A true quantum technology revolution, that genuinely exploits photons’ exotic nature, requires methods and apparatus that work unconditionally. The main barrier is the extreme fragility of quantum properties due to unavoida ....Unconditional photonic entanglement verification and quantum metrology using fast, ultra-high-efficiency photon detectors. Scientists can currently only give in-principle demonstrations of the powerful advantages offered by the quantum physics of photons – particles of light. A true quantum technology revolution, that genuinely exploits photons’ exotic nature, requires methods and apparatus that work unconditionally. The main barrier is the extreme fragility of quantum properties due to unavoidable losses. This project will overcome this barrier by developing innovative loss-tolerant protocols and devices that unconditionally show and exploit quantum effects, both for long-distance applications and ultra-precise measurement technologies. This collaboration will bring the world’s best photon detectors to Australia, as a key resource for this work and for future research.Read moreRead less
The physics and biology of hearing in larval fish. Using the zebrafish model and an array of cutting-edge biophysics and neuroscience tools, this project aims to provide the first complete map of a functioning auditory system. This is significant because it has previously been impossible to study the brain at the levels of single cells, circuits, and brain-wide networks simultaneously. Expected outcomes include detailed descriptions of information flow through a simple brain and the ways that br ....The physics and biology of hearing in larval fish. Using the zebrafish model and an array of cutting-edge biophysics and neuroscience tools, this project aims to provide the first complete map of a functioning auditory system. This is significant because it has previously been impossible to study the brain at the levels of single cells, circuits, and brain-wide networks simultaneously. Expected outcomes include detailed descriptions of information flow through a simple brain and the ways that brain cells and circuits communicate to process information. Benefits include knowledge gained about sensory systems in nature, future biomimetic approaches for information processing, and the training of the next generation of Australian researchers in cutting edge optical physics and neuroscience.Read moreRead less

An accelerating journey to the new era of Petabyte optical memory systems. Optical data storage is one of the core aspects of optical information technology which has been globally recognised as one of the next generation high-technology areas that can boost our economy for sustainable development.

Optical data storage is one of the core aspects of optical information technology which has been globally recognised as one of the next generation high-technology areas that can boost our economy for sustainable development. However, the emergence of blue ray or high-definition DVDs has identified that current optical data storage technology will soon approach the limit of the data storage capacity of approximately 100 Gigabytes. The ground-breaking Petabyte data storage technology we will research will result in the storage capacity of 10,000 DVDs in one disc and thus underpin every sector of our modern life such as remote education, portable banking, global e-security and telemedicine as well as lead to enormous economic benefits in Australia.Read moreRead less

This project aims to develop advanced technologies to optically levitate macroscopic (millimetre-sized) objects and nanoscopic (atomically thin) materials. Levitation platforms built by the investigatory team are based on the resonantly amplified radiation pressure of laser beams. This new type of optical levitation can provide ultimate isolation of the systems from external noise, making them extremely responsive to subtle environmental changes. These platforms could be turned into sharp instruments for measuring metrological variables of interest and probing new physics. Quantum optical techniques could be developed to optimise the sensitivity of levitated systems to levels that allow the exploration of quantum and gravitational physics.Read moreRead less
