Abstract
A spin qubit quantum device includes a semiconductor portion having a first region disposed between two second regions; a first control gate disposed in direct contact with the first region and configured to control a minimum potential energy level in the first region, and disposed in direct contact with a first face of the semiconductor portion; and second electrostatic control gates, each disposed in direct contact with one of the second regions and configured to control a maximum potential energy level in one of the second regions, and disposed in direct contact with a second face, opposite to the first face, of the semiconductor portion, The first gate is not aligned with the second gates.
