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
If a spin could torque: quantum force sensing with levitated nanodiamonds. This project aims to detect the tiny twisting forces imparted by a single quantum spin on a host diamond nanocrystal levitating in vacuum. Our team will build both a hypersensitive detector of quantum rotations and the complex theoretical models for quantum spin systems coupled to the mechanical motion of nanometre-sized diamonds. The expected experimental capabilities and knowledge generated by this project will enable w ....If a spin could torque: quantum force sensing with levitated nanodiamonds. This project aims to detect the tiny twisting forces imparted by a single quantum spin on a host diamond nanocrystal levitating in vacuum. Our team will build both a hypersensitive detector of quantum rotations and the complex theoretical models for quantum spin systems coupled to the mechanical motion of nanometre-sized diamonds. The expected experimental capabilities and knowledge generated by this project will enable world-first measurements of quantum effects with unparalleled sensitivity and powerful new quantum sensing paradigms. The project should enable significant benefits, such as incisive tests of the limits of quantum theory and new Australian technology operating at the interface of the quantum and classical worlds.Read moreRead less

Summary
A quantum telescope for extremely high-resolution imaging. This project will combine world-leading Australian signal stabilisation technology with recent developments in quantum sensors to demonstrate the world’s first quantum telescope. This project expects to demonstrate that quantum detectors can feasibly link optical telescopes, separated by hundreds of kilometres, to achieve extremely high-resolution imaging.

This project will combine world-leading Australian signal stabilisation technology with recent developments in quantum sensors to demonstrate the world’s first quantum telescope. This project expects to demonstrate that quantum detectors can feasibly link optical telescopes, separated by hundreds of kilometres, to achieve extremely high-resolution imaging. Expected outcomes are the development of technologies that will enable imaging with resolution more than 20 times better than any existing telescope. This will provide significant benefits for astronomy, space situational awareness, and defence.Read moreRead less
