“…Extending the ideas of controlling the reflection and transmission of a photon by an atom in an array, quantum routers [357][358][359][360][361][362][363][364][365][366][367][368][369][370] are proposed by coupling two different cavity arrays in X-shape [371], T -shape [372][373][374], T -bulge-shape [375,376], Π-shape [377], etc. Routing of photons allows to connect several quantum nodes to build a quantum network.…”

Processing of information and computation undergoing a paradigmatic shift since the realization of the enormous potential of quantum features to perform these tasks. Coupled cavity array is one of the well-studied systems to carry out these tasks. It is a versatile platform to build quantum networks for distributed information processing and communication. Cavities have the salient feature of retaining photons for longer, thereby enabling them to travel coherently through the array without losing them in dissipation. Several research groups have successfully demonstrated the coupling of cavities and implemented various quantum information protocols. These advancements pave the way for implementing cavity arrays for large scale quantum communications and computations. This article reviews theoretical proposals and discusses a few pertinent experimental realizations of quantum information tasks in cavities.

“…However, they mainly paid attention to the influence the spacing between the nanowires. In recent years, a great deal of research work has concentrated on searching for an effective quantum reroute, both in theory [25][26][27][28] and in experiments [23,24,29]. For practical use, there is hope for the realization of a quantum router, which can transport the incoming single photons with the required high feasibility by which the propagating signals can be distributed efficiently to quantum channels.…”

A single photon router with a desired high routing rate is of great importance for quantum networks. Recently, coupling between channeled plasmons and quantum emitters have been widely used to explore the routing feasibility in hybrid systems. As a capable alternative, we suggested a scheme of a single plasmon router using a V-type three-level quantum dot (QD) sandwiched between two plasmonic waveguides. We theoretically investigated the transmission and transfer rates of single plasmons in the complex system via the real-space approach. Our calculations show that the single plasmons from the incident route could be redirected by controlling such parameters as the intensity of the classical field, the detunings and the couplings between the QD and the plasmonic waveguides. Our proposed scheme could be used not only for the design of a single plasmon router but also for the design of quantum switches and quantum couplers in quantum photonic integrated circuits.
