Abstract

We use quantum device modeling based on the three-dimensional self-consistent solution of the Kohn-Sham equation within the local spin density approximation (LSDA) to show that the design of quantum dot devices can be optimized for efficient spin-qubit operation. We also show that the design of a quantum point contact adjacent to laterally coupled planar quantum dots (LCPQD) can be optimized to produce maximum sensitivity to single-electron charging in the quantum dot.
