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

This project aims to experimentally demonstrate a device needed to bus quantum information between defect clusters in large scale quantum computers. Quantum computers could transcend limits of today’s ‘classical’ computers. Diamond is a proven platform for small-scale quantum computing and simple quantum algorithms have already been demonstrated using small clusters of diamond defects. To build a large-scale quantum computer that can realise the potential of quantum computing, a device must be invented to bus quantum information between defect clusters. This project will experimentally demonstrate physical mechanisms that were theoretically identified for the operation of such a device. This is expected to make a quantum bus for large-scale diamond quantum computers possible.Read moreRead less

This project aims to investigate the effects of a fundamental minimum length on the nature of gravity and on how accurately we can make measurements in our world. The key challenge is to combine our best theories of fundamental physics to model what happens at ultra-short distances. This project will generate new knowledge at this interface by using a novel approach inspired by information theory. The expected outcomes are new connections between fundamental limitations on measurements, the nature of gravitation, and ultra-small-scale quantum physics.
