Abstract: 
We introduce a conceptually simple and experimentally feasible method to realize and detect photonic
topological Chern insulators with a one-dimensional circuit quantum electrodynamics lattice. By periodically
modulating the couplings in this lattice, we show that this one-dimensional model can be mapped into a
two-dimensional Chern insulator model. In addition to allowing the study of photonic Chern insulators, this
approach also provides a natural platform to realize experimentally Laughlin’s pumping argument. Remarkably,
based on the scattering theory of topological insulators and input-output formalism, we find that both the photonic
edge state and topological invariant can be unambiguously probed with a simple dissipative few-resonator
circuit-QED network.
