Fast ion shuttling which is robust versus oscillatory perturbations

Understand

Shuttling protocols designed by shortcut-to-adiabaticity techniques may suffer from perturbations and imperfect implementations.

• We study the motional excitation of a single ion shuttled in harmonic traps with time-dependent, "systematic" oscillatory perturbations around the nominal parameters.
• These elementary perturbations could form any other by superposition.
• Robust shuttling strategies are proposed and compared, and optimizations are performed.
