Optimal local control of coherent dynamics in custom-made nanostructures
Abstract
We apply quantum optimal control theory to establish a local voltage-control scheme that operates in
conjunction with the numerically exact solution of the time-dependent Schrodinger equation. The scheme is ¨
demonstrated for high-fidelity coherent control of electronic charge in semiconductor double quantum dots. We
find tailored gate voltages in the viable gigahertz regime that drive the system to a desired charge configuration
with >99% yield. The results could be immediately verified in experiments and would play an important role in
applications towards solid-state quantum computing.
