We report the experimental demonstration of site-selective RF addressing of atoms with sub-wavelength resolution in a spin-dependent optical lattice of double wells. We also show spin-dependent transport: coherent spatial separation of atomic wave packets into adjacent sites according to their internal state. These tools should be useful for quantum information processing with neutral atoms in an optical lattice.
