“…The parameters µ, η and λ are the free energies of the subsystems written in the convention of Ref. [26], σ (i) kl = |k (i)(i) l| are the atomic transition operators, k and l denotes either ground (g) or exited (e) states of the atom and i = 1, 2 labels the cavities. Throughout this paper, the hopping rate ζ will be scaled by the free energy λ in numerical calculations so that in all figures where ζ ≤ 1 corresponds to the local interaction dominant regimes, while ζ > 1 corresponds to the hopping dominant regimes.…”

We examine transfer of particle entanglement and spin squeezing between atomic and photonic subsystems in optical cavities coupled by two-photon exchange. Each cavity contains a single atom, interacting with cavity photons with a two-photon cascade transition. Particle entanglement is characterized by evaluating optimal spin squeezing inequalities, for the cases of initially separable and entangled two-photon states. It is found that particle entanglement is first generated among the photons in separate cavities and then transferred to the atoms. The underlying mechanism is recognized as an inter-cavity two-axis twisting spin squeezing interaction, induced by two-photon exchange, and its optimal combination with the intra-cavity atom-photon coupling. Relative effect of non-local two-photon exchange and local atom-photon interactions of cavity photons on the spin squeezing and entanglement transfer is pointed out.

“…The two-photon exchange interaction [62][63][64] corresponds to the transition |ϕ n,k ↔ |ϕ n,k+2 , which represents (approximately) |k, n − k ↔ |k + 2, n − k − 2 . To the lowest order in g 0 /∆ − we obtain…”

We consider the nonstationary circuit QED architecture in which a single-mode cavity interacts with N > 1 identical qubits, and some system parameters undergo a weak external perturbation. It is shown that in the dispersive regime one can engineer the two-photon exchange interaction by adjusting the frequency of harmonic modulation to (approximately) 2|∆−|, where ∆− is the average atom-field detuning. Closed analytic description is derived for the weak atom-field coupling regime, and numeric simulations indicate that the phenomenon can be observed in the present setups.

“…Here we consider also a one-dimensional CRW; however, the dynamics of the two-level system is governed by twophoton transitions instead [10]. Therefore, no single photon can traverse the entirety of the CRW; rather one must consider the coherent propagation of two or more photons.…”

We consider the coherent propagation of n photons in a one-dimensional coupled-resonator waveguide for n = 2, 3, 4 . . . . The scattering by a three-level atom, which resides in one of the resonators of the waveguide and gives rise to only two-photon transitions, results in a perfect quantum switch that allows either total reflection or total transmission. This is to be contrasted to the case of a single photon inside a one-dimensional resonant waveguide scattered by a two-level system with single-photon transitions where only total reflection can be accomplished; viz. the system behaves only as a perfect mirror but not as an ideal, transparent medium.
