Two-photon optical transitions combined with long-range dipole-dipole interactions can be used for the coherent manipulation of multiatom collective states. We show that it is possible to induce optical resonances accompanied by the generation of entangled superpositions of such atomic states. Resonances of this kind can be used to implement quantum logic gates using optically excited single atoms (impurities) in the condensed phase.
双光子光学跃迁与长程偶极-偶极相互作用相结合,可用于对多原子集体态进行相干操控。我们证明,有可能诱导出光学共振,并伴随产生此类原子态的纠缠叠加。这种共振可用于在凝聚相中利用光激发单原子(杂质)来实现量子逻辑门。
