Abstract: Aspects of the present disclosure relate generally to systems and methods for use in the implementation and/or operation of quantum information processing (QIP) systems, and more particularly, to a double individual-addressing multi-beam Raman system for use in QIP systems. A technique is described in which a first muti-channel modulator (MCM), a first telecentric zoom lens, and a first interleaver that form a first optical path of the Raman system that receives a first array of beams and adjusts the first array of beams to individually address atomic-based qubits in a chain from a first direction. Moreover, a second MCM, a second telecentric zoom lens, and a second interleaver form a second optical path of the Raman system that receives a second array of beams and adjusts the second arrays of beams to individually address the atomic-based qubits in the chain from a second direction different from the first direction.

Abstract: A method of performing a quantum gate operation in an ion trap quantum computing system includes identifying one or more error mechanisms that cause a quantum computational error in a quantum gate operation on a first trapped ion of an ion chain comprising a plurality of trapped ions, wherein the quantum gate operation is performed by applying a first Raman laser beam and a second Raman laser beam, computing a first amplitude of the first Raman laser beam, and a second amplitude of the second Raman laser beam such that the effect of the identified one or more error mechanisms is accounted for, and applying the first Raman laser beam having the computed first amplitude and the second Raman laser beam having the computed second amplitude on the first trapped ion to perform the quantum gate operation on the first trapped ion.
