This talk will describe silicon nanostructures that confine electrons at the SiO2/Si interface and produce quantum dot behavior. These structures combined with single ion implantation provide a platform for silicon quantum bits. Application of these structures towards circuit model and ground state quantum computing approaches will be discussed.
