- Abstract: We propose protocols to prepare highly excited energy eigenstates of a
trapped ion in a harmonic trap which do not require laser pulses to induce
transitions among internal levels. Instead the protocols rely on smoothly
deforming the trapping potential between single and double well configurations.
The speed of the changes is set to minimize non-adiabatic transitions by
keeping the adiabaticity parameter constant. High fidelities are found for
times more than two orders of magnitude smaller than with linear ramps of the
control parameter. Deformation protocols are also devised to prepare
superpositions to optimize interferometric sensitivity, combining the ground
state and a highly excited state.
