Abstract
A method of performing an entangling operation in a chain of trapped ions includes selecting a gate duration value and a detuning value of a pulse sequence used to perform an entangling gate operation on a first ion and a second ion, measuring frequencies of collective motional modes of the chain, computing a value of an entangling interaction between the first and second ions and values of phase space trajectories of the collective motional modes, based on the selected gate duration value, the selected detuning value, and the measured frequencies of the collective motional modes, determining an intensity of each pulse segment in the pulse sequence based on the computed values, generating the pulse sequence by connecting the pulse segments, each pulse segment having the determined intensity and a pulse shape with ramps formed using a spline, and applying the generated pulse sequence to the first and second ions.
