Abstract
A pair of acousto-optic deflectors (AODs) is used to steer a pair of laser beams to address individual atoms of an array of atoms so that the beams can conditionally induce a 2-photon transition between the atom's quantum energy levels. The first beam is deflected into a +1 diffraction order, resulting in an AOD output beam with a frequency greater than that of the respective AOD input beam. The second beam is deflected into a −1 diffraction order so that the AOD output beam has a frequency less than that of the respective AOD input beam. The equal and opposite frequency changes compensate it other so that the sum of the output frequencies remains resonant with the transition of interest. Thus, AODs can be used to steer laser beams to address individual atoms of an atom array.
