Superconducting quantum circuits constitute the next generation of nano-electronics. They find application in medicine, biology and geophysics; from mapping mineral deposits to imaging heart function, and are a promising candidate for quantum information processing and high speed electronics. A major loss mechanism within a Josephson junction (which forms the basis of a quantum circuit) is caused by intrinsic two-level defects. What is not known is the true microscopic nature of these defects, although there are many theories. This project aims to unravel this mystery using detailed theoretical and computation analysis based on precision experimental characterisation.Read moreRead less
Controlled atomic chaos: breaking through the disorder roadblock for the next generation low power transistors. Computer chip miniaturisation has reached a critical barrier: performance and power consumption are now seriously hampered by atomic level disorder in the materials. The project aims to understand and resolve the disorder problem and establish Australia's place in the international roadmap with disruptive improvement of device speed and power consumption.

A low-temperature scanning tunnelling microscope: The project aims to establish a facility to exploit the spectroscopic and spatial resolution of an ultra-low temperature scanning tunnelling microscope in conjunction with atomically controlled dopant engineering. In a variety of experiments the research team will explore ultra-scaled transistors, quantum information science devices, and engineered quantum matter. Improving our ability to investigate semiconductor materials at the atomic scale impacts fields ranging from electronics, telecommunication, quantum information to renewable energy research and puts Australia at the forefront of the field of controlled atomic systems in semiconductors.Read moreRead less
