Abstract: Quantum computers, systems, apparatuses, and/or the like and corresponding methods for de-exciting coherent motional modes of an atomic object crystal confined by an atomic object confinement apparatus. One or more voltage sources are controlled to cause a waveform to be applied to an array of electrodes of the atomic object confinement apparatus. Application of the waveform to the array of electrodes causes each of the one or more transport operations to be performed on the respective atomic object crystal and causes de-excitation of at least one coherent motional mode of the respective atomic object crystal corresponding to the at least one of the one or more transport operations. The respective shim waveform configured to de-excite the at least one coherent motional mode may be determined based on a parameterized shim waveform and a calibration process for determining parameters corresponding to the atomic object confinement apparatus.
