Abstract
Two-photon optical transitions combined with long-range dipole-dipole inter actions can be used for the coherent manipulation of multiatom collective s tates. We show that it is possible to induce optical resonances accompanied by the generation of entangled superpositions of such atomic states. Reson ances of this kind can be used to implement quantum logic gates using optic ally excited single atoms (impurities) in the condensed phase.
