    "abstract": "Dissipation-free photon-photon interaction at the single photon level is\nstudied in the context of cavity electromagnetically induced transparency\n(EIT). For a single multilevel atom exhibiting EIT in the strong\ncavity-coupling regime, the anharmonicity of the atom-cavity system has an\nupper bound determined by single atom-photon coupling strength. Photon blockade\nis inferred to occur for both single and multi-atom cases from the behaviour of\ntransition rates between dressed states of the system. Numerical calculations\nof the second order coherence function indicate that photon antibunching in\nboth single and two-atom cases are strong and comparable.",
