- Abstract summary: We introduce an extended version of the Rice-Mele model with all-to-all exchange interactions.
We demonstrate the topologically protected and dispersionless transport of a photon on a one-dimensional emitter chain.
We observe that despite the long-ranged character of the dipole-dipole interactions, topological pumping facilitates the transport of a photon with a fidelity per cycle which can reach 99.9%.

- Abstract: We establish the concept of topological pumping in one-dimensional systems with long-range interactions and apply it to the transport of a photon in quantum optical systems. In our theoretical investigation, we introduce an extended version of the Rice-Mele model with all-to-all exchange interactions. By analyzing its properties, we identify the general conditions for topological pumping and demonstrate the topologically protected and dispersionless transport of a photon on a one-dimensional emitter chain. As concrete examples, we investigate three different popular quantum optics platforms, namely Rydberg atom lattices, dense lattices of atoms excited to low-lying electronic states, and atoms coupled to waveguides, using experimentally relevant parameters. We observe that despite the long-ranged character of the dipole-dipole interactions, topological pumping facilitates the transport of a photon with a fidelity per cycle which can reach 99.9%. Moreover, we find that the photon pumping process remains topologically protected against local disorder in the coupling rates.
