Building Schrodinger's cat: large-scale entanglement of trapped ions. Where does the microscopic quantum world leave off and the normal world begin? The project will expand the boundaries of the quantum realm by building the largest quantum objects ever assembled and put them to work in computing and cryptography. These quantum devices will help Australia lead the race for future information technologies.

Summary
Precision laser levitation for quantum metrology and gravitational sensing. Precision laser levitation for quantum metrology and gravitational sensing: This fellowship project aims to levitate macroscopic objects using only laser beams, to provide a new tool to test physics theories. Strong laser beams can exert sufficient force to counteract gravity and make an object levitate. In contrast to other forms of levitation, laser levitation is scatter-free and can preserve system coherence. It has s ....Precision laser levitation for quantum metrology and gravitational sensing. Precision laser levitation for quantum metrology and gravitational sensing: This fellowship project aims to levitate macroscopic objects using only laser beams, to provide a new tool to test physics theories. Strong laser beams can exert sufficient force to counteract gravity and make an object levitate. In contrast to other forms of levitation, laser levitation is scatter-free and can preserve system coherence. It has superior optical and mechanical quality factors and complete information of the system dynamics is retained. This allows laser levitation to be turned into a highly controllable and ultra-sensitive device capable of detecting minute environmental changes. This research aims to probe the relationship between quantum and gravitational physics and develop laser levitation into a precision instrument for the sensing of gravity. Laser levitation has the potential to be developed into technology for mineral exploration and environmental sensing.Read moreRead less
Coherent Laser Levitation for Precision Sensing and Enabling Science. When light collides with matter, it may exert a force called radiation pressure. This project aims to use radiation pressure to levitate a small mirror. Using a tripod of laser beams, it is possible to levitate and trap the mirror in a stable position. Radiation pressure has been used before to levitate, but previous work has always involved scattering light from the levitating object. This project proposes the use of a high q ....Coherent Laser Levitation for Precision Sensing and Enabling Science. When light collides with matter, it may exert a force called radiation pressure. This project aims to use radiation pressure to levitate a small mirror. Using a tripod of laser beams, it is possible to levitate and trap the mirror in a stable position. Radiation pressure has been used before to levitate, but previous work has always involved scattering light from the levitating object. This project proposes the use of a high quality mirror, allowing the collection of the reflected light and the accurate measurement and control of the position of the mirror as it floats on the laser beams. Using the unique properties of the floating mirror, it will be possible to search for signatures of quantum gravity and develop tools for ultra-precision metrology.Read moreRead less
Interferometry beyond the Standard Quantum Limit. This research aims to realise measurements below the Standard Quantum Limit (SQL) using advanced quantum optic and opto-mechanical techniques. This is of fundamental interest as the SQL is yet to be observed for a macroscopic object. It is also of particular significance to second generation gravitational wave detectors which are expected to be limited by the SQL. This project will develop an opto-mechanical sensor capable of achieving SQL sensit ....Interferometry beyond the Standard Quantum Limit.

This is of fundamental interest as the SQL is yet to be observed for a macroscopic object. It is also of particular significance to second generation gravitational wave detectors which are expected to be limited by the SQL. This project will develop an opto-mechanical sensor capable of achieving SQL sensitivity as well as develop and test techniques to surpass the SQL. These techniques will be directly applicable to long base-line gravitational wave detectors.Read moreRead less
Enhancing the science reach of second generation interferometric gravitational wave detectors through innovative mirror design and control. Predicted by Einstein, gravitational waves promise to unlock the secrets of the universe just as seismic measurements unlocked the secrets of the Earth's interior. Scientists are on the brink of detecting these waves. This research aids that effort by developing Australian technologies which allow specific gravitational wave sources to be targeted.
