摘要：
This paper proposes two schemes to generate the two-atom Knill-Laflamme-Milburn states with a strong coupling cavity-fiber system and the cavity-assisted single-photon input-output process, respectively. The significant logical operations for the generation are constructed accurately. The resonant interactions between atoms and photons in the two schemes imply a relatively short operation time, and the probabilities of successful generation are near to unity under the current experimental conditions.
