Dopant engineering of diamond for quantum sensing technologies. Doped diamonds are central to a growing range of quantum-sensing technologies for future industries, including medical and defence. These diamonds must be doped with both an electron donors and active 'quantum-defects' to operate. Within existing devices, the electronic donors also create parasitic magnetic noise, due to their magnetic-spin properties. In this project we aim to investigate the growth of diamond with new electronic d ....Dopant engineering of diamond for quantum sensing technologies. Doped diamonds are central to a growing range of quantum-sensing technologies for future industries, including medical and defence. These diamonds must be doped with both an electron donors and active 'quantum-defects' to operate. Within existing devices, the electronic donors also create parasitic magnetic noise, due to their magnetic-spin properties. In this project we aim to investigate the growth of diamond with new electronic donors, aiming for spin-free and thus noise-free dopant properties. This should provide significant benefits to defence capability, through enhanced magnetic anomaly detection in naval environments, and health outcomes, through neural sensing of brain signals at room temperature.Read moreRead less
Synthesis of enriched silicon for long-lived donor quantum states. We have discovered a method to make silicon highly enriched in the desirable spin-zero isotope using readily available ion implantation tools. This “semiconductor vacuum” is essential for building future quantum computer devices using the quantum spin of millions of implanted atoms with revolutionary capabilities. We have demonstrated long-lived implanted donor atom quantum states in prototype material, made possible by the deple ....Synthesis of enriched silicon for long-lived donor quantum states. We have discovered a method to make silicon highly enriched in the desirable spin-zero isotope using readily available ion implantation tools. This “semiconductor vacuum” is essential for building future quantum computer devices using the quantum spin of millions of implanted atoms with revolutionary capabilities. We have demonstrated long-lived implanted donor atom quantum states in prototype material, made possible by the depletion of background spins in natural silicon and now aim to push the enrichment to greater extremes. We will integrate the extreme material into functional devices that use electrically detected electron spin resonance to probe exceptionally durable quantum states and open a near-term pathway to large-scale devices.Read moreRead less
Multidimensional Coherent Spectroscopy of Strongly Correlated Materials. By applying new types of spectroscopy, this project aims to address the gaps in our understanding of how remarkable macroscopic properties, such as superconductivity, emerge from the fundamental interactions in strongly correlated electron materials. This project will combine theory and experiment to develop a pathway by which multidimensional coherent spectroscopy can disentangle the competing interactions that make these ....Multidimensional Coherent Spectroscopy of Strongly Correlated Materials. By applying new types of spectroscopy, this project aims to address the gaps in our understanding of how remarkable macroscopic properties, such as superconductivity, emerge from the fundamental interactions in strongly correlated electron materials. This project will combine theory and experiment to develop a pathway by which multidimensional coherent spectroscopy can disentangle the competing interactions that make these materials so complex, but also potentially useful. By delivering an understanding of the interplay between different microscopic processes, the project will make it more feasible to control them. This will allow for the design new controllable quantum materials that can be the basis for future technologies.Read moreRead less
Chemical mapping of materials at the atomic scale. This project will develop a method for measuring the chemical composition of technologically important nanomaterials. This capability will provide Australian scientists with an advanced method for the characterisation of materials and will help them to develop new and better materials for future applications.
