  We address the technical challenges when performing quantum information
experiments with ultracold Rydberg atoms in lattice geometries. We discuss the
following key aspects: (i) The coherent manipulation of atomic ground states,
(ii) the coherent excitation of Rydberg states, and (iii) spatial addressing of
individual lattice sites. We briefly review methods and solutions which have
been successfully implemented, and give examples based on our experimental
apparatus. This includes an optical phase-locked loop, an intensity and
frequency stabilization setup for lasers, and a nematic liquid-crystal spatial
light modulator.
