“…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.

“…[8][9][10][11][12] With the ideal platform, quantum routing of single photons is also investigated, where waveguide is utilized as the quantum channel, and the photon signal transport is controlled effectively via the strong light-matter interactions. Accordingly, numerous theoretical [13][14][15][16][17][18][19][20][21][22][23][24][25][26] and experimental [27][28][29][30] investigations on the quantum routing of single photons have been demonstrated in many waveguide-QED systems. For example, Zhou et al examined the single-photon quantum routing properties in an Xshaped coupled-resonator waveguide (CRW), and showed that efficient routing can be implemented between two quantum channels with the help of a classical field.…”

Quantum routing in a T-bulge-shaped waveguide system coupled with a driven cyclic three-level atom and a two-level atom is investigated theoretically. By employing the discrete-coordinate scattering method, exact expressions of the transport coefficients along three ports of the waveguide channels are derived. Our results show that bidirectional high transfer-rate single-photon routing between two channels can be effectively implemented, with the help of the effective potential generated by two atoms and the external driving. Moreover, multiple band zero-transmission emerges in the scattering spectra, arising from the quantum interferences among photons scattered by the boundary and the bulged resonators. The proposed system may suggest an efficient duplex router with filtering functions.
