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.
Memory and light for integrated quantum systems. Optical quantum information technologies have the potential to change the way we work and play, but there are problems to be overcome: we lack both a memory for quantum information and reliable light sources that can be integrated into quantum networks. This project addresses both these issues and will bring quantum technologies closer to market.
A Quantum Matterwave Vortex Gyroscope for Ultrastable Rotation Sensing. This project aims to investigate the basic science underpinning a new rotation sensing technology based on matterwave vortices. Current gyroscopes are susceptible to long-term calibration drifts, which limit their applicability on long timescales where re-calibration is not practical or possible. This project expects to build a matterwave vortex gyroscope and demonstrate that it offers unparalleled long-term stability over ` ....A Quantum Matterwave Vortex Gyroscope for Ultrastable Rotation Sensing. This project aims to investigate the basic science underpinning a new rotation sensing technology based on matterwave vortices. Current gyroscopes are susceptible to long-term calibration drifts, which limit their applicability on long timescales where re-calibration is not practical or possible. This project expects to build a matterwave vortex gyroscope and demonstrate that it offers unparalleled long-term stability over `classical’ gyroscopes based on mechanical and/or optical technology. This could deliver new navigation capabilities, benefitting Australia’s defence forces and nascent space technology industry, as well as enabling slow timescale precision gravimetry for mineral exploration, hydrology, and geology.

Cold positron interactions with ultracold rubidium atoms. Antiparticles and antimatter have progressed from theory and science fiction to become an important and exciting area of pure and applied science.

Antiparticles and antimatter have progressed from theory and science fiction to become an important and exciting area of pure and applied science. This fundamental atomic physics project aims to further study how antimatter and matter interact by providing the first comprehensive experimental results for the interaction of positrons (the electron anti-particle) with trapped rubidium atoms in an innovative combination of two cutting-edge atomic physics techniques. It aims to provide measurements of many fundamental interaction quantities and for collisions between matter and antimatter. This will look to test the latest quantum theoretical approaches and further our understanding of the uses of antimatter in medical and materials science.Read moreRead less
Time-space resolved photoelectron emission to control molecular processes. This project aims to resolve simultaneously the timing and space localisation of photoelectron emission from atoms and molecules as a means for targeted breaking of molecular bonds. Existing techniques determine the timing and spatial characteristics of photoemission independently. The simultaneous time-space resolution will allow for the precise manipulation of photoelectrons by a sequence of phase-stabilised laser pulse ....Time-space resolved photoelectron emission to control molecular processes. This project aims to resolve simultaneously the timing and space localisation of photoelectron emission from atoms and molecules as a means for targeted breaking of molecular bonds. Existing techniques determine the timing and spatial characteristics of photoemission independently. The simultaneous time-space resolution will allow for the precise manipulation of photoelectrons by a sequence of phase-stabilised laser pulses, a technique known as coherent control. The benefit of this project will be the coherently controlled breaking of molecular bonds in oxide, carbonyl and hydrocarbon molecules. The outcome will be a significant step forward in driving complex photochemical reactions in industry.Read moreRead less

Summary
Thinking outside the box: spherical geometry in chemistry and physics. Spherical models are extremely powerful for understanding, explaining and predicting physical and chemical phenomena. This work takes advantage of the spherical model superiority to tackle some fundamental unsolved problems in physics and chemistry, and this will lead to new insights in their field.
Using high-resolution lasers to test quantum electrodynamics. High-precision laser-based measurements of atomic and molecular structure are benchmarks for our fundamental understanding of matter. This project will undertake state-of-the-art experiments on atomic helium, to test and challenge current theoretical predictions of fundamental quantum-electrodynamic properties for helium and for more complex atoms.

Accurate quantum chemistry via quadrature and resolution. This project seeks to develop two radical new approaches to the integration problem which lies at the heart of quantum chemistry. The first approach will systematically exploit the fact that the energy integral is a totally symmetric function of the electronic coordinates. The second approach will systematically develop one-electron resolutions of the many-electron operators that appear in explicitly correlated quantum chemical methods. A ....Accurate quantum chemistry via quadrature and resolution. This project seeks to develop two radical new approaches to the integration problem which lies at the heart of quantum chemistry. The first approach will systematically exploit the fact that the energy integral is a totally symmetric function of the electronic coordinates. The second approach will systematically develop one-electron resolutions of the many-electron operators that appear in explicitly correlated quantum chemical methods. After developing the underlying theory of these two approaches, this project will implement them efficiently in accessible software, so that they can be used by the scientific community to perform more accurate molecular modelling than has been possible in the past.Read moreRead less
Improved density functional approximations from a new model of the uniform electron gas. By studying the way that electrons move on the surface of a sphere, this project will systematically construct new methods for studying and predicting chemistry using the laws of quantum mechanics. The work will pave the way for even complicated chemical reactions to be investigated using standard PC or Mac computers.
