A realistic protocol for implementing quantum logic with laser-trapped neutral alkali-metal atoms using electric dipole-dipole interactions is presented. Both diagonal and exchange interactions can be designed to create entanglement between internal degrees of freedom. Including the hyperfine molecular structure of interacting alkali-metal atoms, it is shown that the universal CPHASE gate can be executed with high fidelity.
