Multiparticle entanglement in a one-dimensional optical lattice using Rydberg-atom interactions

We study the many-atom system in a one-dimensional optical lattice with Rydberg interactions. We analyze the coherent excitation of interacting atoms and demonstrate various entanglements between atoms in this system. We also analyze the resonant spectrum for the excitation of entangled atoms. We evaluate the experimental feasibility of the realization of the entanglement.
