“…There are several advantages of non-resonant atom-field interactions than the resonant one. For example, generation of cat states [145,146] and superposition of number states [141], nondemolition measurement of photon number [145], realization of quantum phase gate [245,246], generation of optical nonlinearity [247], control of heat transfer [248], generation of highly bunched photons [249], reading single-qubit states [250], demonstration of universal quantum copying machine [251] etc. are possible with non-resonant interaction.…”

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.

We propose an experimental scheme for the measurement of entanglement between two two-level atoms. Our scheme requires one of the two entangled atoms to interact with a cavity field dispersively, and we show that by measuring the zero time-delay secondorder coherence function of the cavity field, one can measure the concurrence of an arbitrary Bell-like atomic two-qubit state. As our scheme requires only one of the atoms to interact with the measured cavity, the entanglement quantification becomes independent of the location of the other atom. Therefore, our scheme can have important implications for entanglement quantification in distributed quantum systems.

[48] The setup shown in Figure 1 consists of a beam splitter and a detection system for the purpose of measuring zero time-delay second-order coherence function of the field leaking out of the first cavity.…”
