“…It is also possible to control the transfer of photons by placing an atom in any one of the cavities in the array [324,[341][342][343][344][345][346][347][348][349][350]. The presence of an atom in the array either reflects or transmits the photon depending on the detuning between the atom and cavity [320,351,352].…”

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.

“…This model has been used in cavity quantum electrodynamics (QED) to generate "macroscopic" qubits [27] and in the scattering of two coherent photons inside a one-dimensional coupled-resonator waveguide that operates as an ideal quantum switch [28]. More recently, the model has been applied to two-photon exchange between two separate cavities [29] with each cavity containing a three-level atom in a cascade (or ladder) configuration [30] and coupled via a two-photon hopping interaction [29].…”

The generation of entanglement between two identical coupled cavities, each containing a single three-level atom, is studied when the cavities exchange two coherent photons and are in the N = 2,4 manifolds, where N represents the maximum number of photons possible in either cavity. The atom-photon state of each cavity is described by a qutrit for N = 2 and a five-dimensional qudit for N = 4. However, the conservation of the total value of N for the interacting two-cavity system limits the total number of states to only 4 states for N = 2 and 8 states for N = 4, rather than the usual 9 for two qutrits and 25 for two five-dimensional qudits. In the N = 2 manifold, two-qutrit states dynamically generate four maximally entangled Bell states from initially unentangled states. In the N = 4 manifold, two-qudit states dynamically generate maximally entangled states involving three or four states. The generation of these maximally entangled states occurs rather rapidly for large hopping strengths. The cavities function as a storage of periodically generated maximally entangled states.

“…It is interesting and important to investigate the photon-photon and photon-polariton scattering processes. Many efforts related to few-body dynamics mainly focused on multi-photon transports through coupled-cavity QED systems 7 8 9 10 11 12 13 14 15 16 17 18 19 , while a few works dealt with the formation of bound state 20 21 22 . So far, what happens when a photon collides with a polariton is still an open question.…”

We study the scattering problem of photon and polariton in a one-dimensional coupled-cavity system. Analytical approximate analysis and numerical simulation show that a photon can stimulate the photon emission from a polariton through polariton-photon collisions. This observation opens the possibility of photon-stimulated transition from insulating to radiative phase in a coupled-cavity QED system. Inversely, we also find that a polariton can be generated by a two-photon Raman scattering process. This paves the way towards single photon storage by the aid of atom-cavity interaction.
