Quantum Computation: From Electron to Qubit

The characterization of electron states for quantum computing with electrons on liquid He requires several proprietary components. Two of those are a low-T, low noise microwave bolometer and submicron electrode array for electron localization and control of the confinement potential. This project will investigate the feasibility of constructing an InSb hot electron bolometer from commercial materials using standard fabrication technologies. If possible, several prototypes will be constructed and tested. The electrode array (or pad) design, field calculations, signal analysis, and fabrication process is the main goal. Once these are implemented, proof of principle tests and single qubit gate operations will be attempted.
