We experimentally realize Rydberg excitations in Bose-Einstein condensates of rubidium atoms loaded into quasi one-dimensional traps and in optical lattices. Our results for condensates expanded to different sizes in the one-dimensional trap agree well with the intuitive picture of a chain of Rydberg excitations. We also find that the Rydberg excitations in the optical lattice do not destroy the phase coherence of the condensate, and our results in that system agree with the picture of localized collective Rydberg excitations including nearest-neighbour blockade.

We present an experimental study of Rydberg excitations of rubidium Bose Einstein condensates loaded in a quasi-one dimensional potential (dipole trap) and in periodic potentials (optical lattices). The excitation of Rydberg atoms in periodic potentials is one of the possible paths towards reaching the scalability requirements in quantum computation devices, with quantum gates based on the dipole blockade effect.
