Abstract: A method of performing a computational process using a quantum computer includes generating a laser pulse sequence comprising a plurality of laser pulse segments used to perform an entangling gate operation on a first trapped ion and a second trapped ion of a plurality of trapped ions that are aligned in a first direction, each of the trapped ions having two frequency-separated states defining a qubit, and applying the generated laser pulse sequence to the first and second trapped ions. Each of the plurality of laser pulse segments has a pulse shape with ramps formed using a spline at a start and an end of each of the plurality of laser pulse segments.

Abstract: A method of performing a computation using a quantum computer includes modulating motional mode structures of a plurality of trapped ions, each of the plurality of trapped ions having two frequency-separated states defining a qubit, computing a detuning frequency function and an amplitude function of a laser pulse to cause entangling interaction between a pair of trapped ions of the plurality of trapped ions, and performing a quantum computation in the quantum computer by applying a laser pulse having the computed detuning frequency function and the amplitude function to the pair of trapped ions for a gate duration.
