This paper uncovers radiative topological biphoton states in a spatially-modulated qubit array coupled to a waveguide. The topology originates from nontrivial bound-state bands which are characterized by the Chern number in the parameter space created by the center-of-mass momentum and modulation phase being a synthetic dimension.
