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.

This project aims to understand ion-electron interactions relevant to bioelectronics, and create transducing interfaces. Bioelectronics is a frontier field which aims to connect biological systems with modern electronics and so create biomedical devices. Transducing ion and electron signals using a biocompatible functional interface is difficult since ion and electron physics are different.

The stretch goal is to test this new logic with a biological neuronal model. The project could deliver new science and interfacing elements to integrate tissue and circuitry, and demonstrate these in a real biological model.Read moreRead less
