Deterministic Routing of Single Photons in Multi-emitter Chiral Waveguide QED

On-demand single-photon generation and propagation are one of the key requirements in performing several quantum information processing protocols. Gonzalez et al. have recently proposed deterministic routings of few photons in double-waveguide quantum electrodynamics (QED) utilizing preferential photon emissions into waveguide modes (chirality). Extending their work, in this study, we ask the question that how the performance of such a single-photon quantum router involving chiral waveguides alters in the many-emitter regime. In particular, we ask the question that can we gain better control of routing phenomena in the presence of many-emitters? With the recent developments in scalability of circuit QED platforms, we believe that our work can find applications in near future quantum networking and quantum computing experiments.
