Modelling Superconducting Quantum Devices. The capability to incorporate quantum mechanical systems into electronic circuits leads to devices with fundamentally new properties. These devices are very sensitive to their environment, so can be used as sensitive sensors. In the extreme, with many such devices connected together, it would lead to a full scale quantum computer, which has the capacity to perform tasks that are unfeasible on an ordinary computer. This proposal aims to characterise ....Modelling Superconducting Quantum Devices.

The project aims to use powerful theoretical and experimental methods to resolve the controversy that surrounds reports of massive hydrogen absorption by nanostructured carbons, by understanding why particular structures should or should not absorb hydrogen atoms or molecules. We will particularly study and model intercalated graphite and nanotubes made in Australia. Their hydrogen capacity will be compared to the US DOE target of 6.5 weight percent for viable automotive hydrogen fuel storage. Reproducibly exceeding this target would constitute a great advance in the field.Read moreRead less
