We study transport of time-bin entangled photon pairs in a 2D topological photonic system of coupled ring resonators. We show that the transport through edge bands preserves temporal correlations of input photons. Furthermore, edge transport is robust against system disorder and only marginally affects the temporal correlations of photons. In contrast, transport through bulk band leads to unwanted bunching/anti-bunching of photons and the probability of bunching/anti-bunching increases with increasing disorder. Finally, we discuss our experimentally efforts to demonstrate the robustness of edge states for quantum transport.
