Ultracold atoms confined in an optical lattice may be utilized to model complex condensed matter systems, and are a leading candidate for applications in quantum information science.   We present progress on a new experimental setup that allows for the manipulation of individual atoms confined in a Hubbard regime optical lattice.  A combination of intra-vacuum, high-numerical aperture optics and optically-induced position-dependent energy shifts should enable single-site selectivity in the lattice, allowing advanced quantum information protocols to be implemented.  The high resolution imaging of the system should also facilitate the observation of quantum phase transitions, and other complex dynamics.
