Abstract

We study the deterministic entanglement of a pair of neutral atoms using pairwise dipole-dipole couplings in a state dependent trap. By bringing atoms together pairwise and inducing state selective interactions, multiparticle entanglement of atoms in an optical lattice can be realized. The main source of decoherence is spontaneous emission which can be made negligible if the two atom interactions are performed fast compared to the scattering rate. A figure of merit is derived for the fidelity of entanglement including molecular interactions.
