We propose to develop and fabricate an optical scanner required to address a 2-D array of trapped Rubidium atomic qubits with two lasers simultaneously. One of the most scalable approaches to quantum information processing (QIP) is Optical addressing of arrays of trapped atoms. This is done with focused spots using tuned lasers which program initial states and implement 2-quibt gates. High spatial resolution of this approach will allow, simultaneously, the individual trapping of ions/atoms to be addressed and the spectral selectivity of stabilized lasers addressing these atomic transitions. The current approaches to laser beam scanning fall short of speed, efficiency, and Doppler-free operation required for QIP. We propose to design and optimize novel acousto-optic scanner system which will allow Doppler-free operation with high speed and reasonably good efficieny. In addition our novel approach to 2-color deflectors enables simultaneous multiple beam operation and is compatible with 2-D scanning to 100x100 atom arrays. The proposed multi-beam acousto-optic scanner system will be optimized for dual wavelengths at 480 nm and 780 nm, but the design architecture will have the potential to operate in a variety of visible and near-IR wavelengths.
