Original Abstract Submitted
a qubit device or system having isolated bottom corner gates includes a semiconductor substrate and a semiconductor fin perpendicularly adjoining a top surface of the substrate. the qubit device also includes a first gate located at a first corner between a first side of the fin and the top surface of the substrate, and a second gate located at a second corner between a second, opposite side of the fin and the top surface of the substrate. the first and second gates are electrically isolated from each other and used to control a first quantum dot near the top of the fin. a third gate located at the first corner has a contact for accumulating a channel to facilitate charge transport to and from a second quantum dot located near the bottom of the fin accumulated using the first and second gates.
