Such nanomechanical computers could extend computing performance in space and earth-orbit applications, and in other environments where intense radiation causes digital electronics to fail. The project intends to utilise recent advances in nanomechanics and nanofabrication to demonstrate all key nanomechanical circuit elements, including transistors, logic gates, memories and analogue-to-digital converters and to deliver a roadmap for commercialisation of the technology in Australia. The expected outcome of this project is the development of the underpinning nanotechnologies, predicted to have wide uses in sensing, health and communications,and which could improve heat management and energy efficiency in future computers.

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 develop an artificial atom in diamond that can connect to other nodes in a network. Network connectivity and data distribution are increasingly important in today's information economy. Tiny glowing artificial atoms in coloured diamonds can receive, store and send information in a network using laser light and microwaves. Because they work at the level of individual atoms and photons, they can use quantum-weirdness to achieve feats impossible even for supercomputers on the classical internet. The proposed device is expected to make it easier to construct technologies that move beyond the limitations of existing infrastructure thus satisfying the unmet core requirements for a quantum network.Read moreRead less
