This project aims to address the issue of designing and engineering better single-photon sources based on atomic defects in solids, a crucial building block for many quantum technologies. Using advanced first-principles quantum mechanical theories and calculations, the project expects to produce fundamental knowledge of key mechanisms and properties, and to use this to inform the design of new atomic defects for tailored applications as quantum emitters. The expected outcomes, including novel methodologies, will contribute to different research areas, from condensed matter and materials physics to quantum science and technology. This project should provide significant benefits in accelerating quantum technology innovation in Australia.Read moreRead less
Cost-efficient 2D heterostructures for solar overall water splitting. This project aims to develop novel processes to enable water splitting to generate hydrogen and oxygen under sunlight using cost-efficient 2D van der Waals heterostructures. Enhanced optical absorption and reduced charge transfer distance across the interface are expected to improve the photocatalytic activity.

This project will exploit recent breakthroughs in materials growth, theoretical physics and micromagnet technology to design and build a new platform for future quantum devices and topological quantum computers. Instead of using exotic materials, we will fabricate hybrid superconductor-semiconductor devices with conventional silicon and germanium semiconductors, using the same nanofabrication techniques that industry uses to create integrated circuits. The outcome will be an entirely new approach to hosting topological modes, in an architecture that can be scaled to make topological based qubits, using industrially compatible semiconductors.

Information transfer in topological matter: how relativity speeds up memory. In the 21st century our economy and security rely on fast information processing, which requires state-of-the-art computer memory. Emerging memory technologies rely on magnets, which retain data during power outages and switch faster than currently used semiconductor devices. This Fellowship will establish a breakthrough paradigm for ultra-fast information processing using magnets and newly-discovered topological materi ....Information transfer in topological matter: how relativity speeds up memory. In the 21st century our economy and security rely on fast information processing, which requires state-of-the-art computer memory. Emerging memory technologies rely on magnets, which retain data during power outages and switch faster than currently used semiconductor devices. This Fellowship will establish a breakthrough paradigm for ultra-fast information processing using magnets and newly-discovered topological materials. It will develop a computational tool to enhance the switching rate of devices incorporating topological materials that emulate industry blueprints for memory building blocks. If successful, it will vastly improve the speed and functionality of computer memory, logic elements, artificial intelligence devices and sensors.Read moreRead less
A new spin on semiconductor quantum information technology. Future advances in computer technology will exploit quantum physics to deliver increased computational power, either through new materials or quantum information approaches. However although half of the 100 billion transistors in your iphone use holes to operate, most semiconductor quantum research has focussed on electrons.

Future advances in computer technology will exploit quantum physics to deliver increased computational power, either through new materials or quantum information approaches. However although half of the 100 billion transistors in your iphone use holes to operate, most semiconductor quantum research has focussed on electrons. Holes have completely different quantum spin properties than electrons; recent advances show holes have highly desirable properties for spin based quantum information. This project will work with leading European laboratories to develop quantum computer components based on hole spin in quantum dots in industrially relevant semiconductors, and demonstrate a pathway towards a scalable quantum computer architecture.
