Abstract
A method of performing an entangling gate operation using a quantum computer system includes configuring, by a classical computer, an amplitude function of an amplitude-modulated laser pulse over a plurality of time segments to cause entangling interaction between a pair of trapped ions of a plurality of trapped ions, each of the plurality of trapped ions having two frequency-separated states defining a qubit, where the amplitude function in each time segment is splined using a set of basis functions and associated control parameters, and performing an entangling gate operation between the pair of trapped ions by applying, by a system controller, an amplitude-modulated laser pulse having the configured amplitude function to the pair of trapped ions.
