    "abstract": "We have investigated the two-photon nonlinearity at general cavity QED\nsystems, which covers both weak and strong coupling regimes and includes\nradiative loss from the atom. The one- and two-photon propagators are obtained\nin analytic forms. By surveying both coupling regimes, we have revealed the\nconditions on the photonic wavepacket for yielding large nonlinearity depending\non the cavity Q-value. We have also discussed the effect of radiative loss on\nthe nonlinearity.",
