We present a computational study of two-photon scattering process in an atom-ring resonator-waveguide QED system. By properly manipulating the operating frequency of incoming photons, we show that two-photon bound state and photon antibunching statistics are generated through resonator-mediated atom-photon interactions. Numerically, we find that mild backscattering and dissipation enhance the quality of generated photonic correlations. In addition, we also report the quantum photonic halo effect and the dissipation-induced photonic correlation transition phenomenon.
