A Transportable Self-referenced Quantum Current Standard on a Silicon Chip. The field of metrological science strives for continuous improvement in precision and reproducibility, a goal only achievable by exploiting the fundamental constants of nature. In electrical metrology, both voltage (V) and resistance (R) standards have reached this milestone, but not current (I). We aim to develop novel self-referenced nanoelectronic charge-pump devices that can generate a highly accurate, error-detectab ....A Transportable Self-referenced Quantum Current Standard on a Silicon Chip. The field of metrological science strives for continuous improvement in precision and reproducibility, a goal only achievable by exploiting the fundamental constants of nature. In electrical metrology, both voltage (V) and resistance (R) standards have reached this milestone, but not current (I). We aim to develop novel self-referenced nanoelectronic charge-pump devices that can generate a highly accurate, error-detectable output current utilising Australian-developed silicon-based single-electron transistor technology. We will undertake high-precision measurements in collaboration with leading European standards institutes and researchers, establishing the technological basis for a new world current standard that is reproducible worldwide.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
ARC Centre of Excellence in Future Low Energy Electronics Technologies. This Centre aims to develop the scientific foundation and intellectual property for new electronics technologies. Decreasing energy use is a major societal challenge, and this Centre aims to meet that challenge by realising fundamentally new types of electronic conduction without resistance in solid-state systems at room temperature. Novel resistance-free electronic phenomena at room temperature are expected to form the basi ....ARC Centre of Excellence in Future Low Energy Electronics Technologies. This Centre aims to develop the scientific foundation and intellectual property for new electronics technologies. Decreasing energy use is a major societal challenge, and this Centre aims to meet that challenge by realising fundamentally new types of electronic conduction without resistance in solid-state systems at room temperature. Novel resistance-free electronic phenomena at room temperature are expected to form the basis of integrated electronics technology with ultra-low energy consumption. This Centre’s development of innovative electronics could put Australia at the forefront of the international electronics industry.Read moreRead less
