1. An optical beam control system, comprising:
a telescope having multiple rotatable mirrors and multiple lenses collectively configured to provide a path to an optical beam that is input into the telescope to produce an output optical beam, the output optical beam being made into parallel optical beams following a diffractive optical element; and
a detector system configured to detect a beam angle, a beam position, or both associated with one of the parallel optical beams being sampled to generate one or more feedback signals to control a rotation of one or more of the rotatable mirrors in the telescope to modify the path and thereby the output optical beam such as to adjust the beam angle, the beam position, or both of the parallel optical beams;
wherein the parallel optical beams are provided to a multi-channel acousto-optic modulator (AOM) in a quantum information processing (QIP) system, the AOM being configured to adjust one or more of the parallel optical beams to control respective atomic qubits in the QIP system.
