Neutral atoms in optical lattices are promising systems for quantum computing in their inherent scalability. It is crucial to manipulate the quantum state of individual qubit without affecting quantum information stored in nearby sites. Here we report on a scheme which arbitrarily changes the superposition state of target sites within a 5×5×5 atom array in an optical lattice, and does not perturb the fidelity of nearby sites at the level of 3 × 10-3.  This single qubit addressing is accomplished using fast reconfigurable laser beams and microwave fields, and the technique can be widely applied elsewhere. I will describe the experiment, two ways to make single qubit gates and our path to a universal quantum computer.
