In particular, we investigate the feasibility of shuttling donor-bound electrons between the impurity in the bulk and the Si-SiO2 interface by tuning an external electric field. We calculate the shuttling time to range from sub-picoseconds to nanoseconds depending on the distance (~ 10-50 nm) of the donor from the interface. Our results establish that quantum control in such nanostructure architectures could, in principle, be achieved.", "revisions": [ { "version": "v2", "updated": "2006-02-15T20:11:46.000Z" } ], "analyses": { "keywords": [ "quantum control", "si-sio2 interface", "donor electrons", "silicon quantum computer architecture", "external electric field" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
