abstract = {Semiconductor quantum dots have shown impressive
breakthroughs in the last years, with single and two qubit
gate fidelities matching other leading platforms and
scalability still remaining a relative strength. However,
due to qubit wiring considerations, mobile electron
architectures have been proposed to facilitate upward
scaling. In this work, we examine and demonstrate the
possibility of significantly outperforming static EDSR-type
single-qubit pulsing by taking advantage of the larger
spatial mobility to achieve larger Rabi frequencies and
reduce the effect of charge noise. Our theoretical results
indicate that fidelities are ultimately bottlenecked by
spin-valley physics, which can be suppressed through the use
of quantum optimal control, and we demonstrate that, across
different potential regimes and competing physical models,
shuttling based single-qubit gates retain significant
advantage over existing alternatives.},
