The objective of the proposed work was to demonstrate that digital switching of the exchange interaction by real space electron transfer will provide a viable method for accurate control of inter-qubit interactions. In order to fix the strength of the exchange interaction at the fabrication stage we proposed a new technology for 3D confinement of electrons by abrupt epitaxial SiSiGe interface. During the course of the project we developed CVD growth of high mobility 2D electron gases in SiSiGe, low damage nanofabrication techniques, in situ cleaning and conformal SiGe re-growth.
