“…The theory outlined in has been generalized for two-photon JCM [17], two-photon JCM with nondegenerate two-photon and Raman transitions [18,19], two-atom JCM [20], two-atom one-mode Raman coupled model 2 [21] and two-atom two-photon JCM [22,23]. Two-photon processes are known to play a very important role in atomic systems due to high degree of correlation between emitted photons.…”

With the Jaynes-Cummings model, we have studied the atom and light field quantum entanglement of multiphoton transition, and researched the effect of initial state superposition coefficient C1, the transition photon number N , the quantum discord δ and the nonlinear coefficient χ on the quantum entanglement degrees. We have given the quantum entanglement degrees curves with time evolution, and obtained some results, which should have been used in quantum computing and quantum information.

“…In relation to the mentioned fact, it may be recalled that, entanglement swapping without BSM method is also of enough interest for people who work in this field [17,[23][24][25]. The quantum interactions can be modeled by Jaynes-Cummings model (JCM) [26][27][28][29][30][31] as well as Tavis-Cummings model (TCM) [32,33]. Based on these models, the interactions can be performed in optomechanical cavity [34,35], instead of the usually used optical cavity.…”

In this paper we consider the quantum repeater protocol for distributing the entanglement to two distant three-level atoms. In this protocol, we insert six atoms between two target atoms such that the eight considered atoms are labeled by 1, 2, • • • 8, while only each two adjacent atoms (i, i + 1) with i = 1, 3, 5, 7 are entangled. Initially, the separable atomic pair states (1,4) and (5,8) become entangled by performing interaction between atoms (2,3) and (6,7) in two optomechanical cavities, respectively. Then, via performing appropriate interaction between atoms (4,5) in an optical cavity quantum electrodynamics (QED) approach, the target atoms (1,8) are finally become entangled. Throughout this investigation, the effects of mechanical frequency and optomechanical coupling strength to the field modes on the produced entanglement and the related success probability are evaluated. It is shown that, the time period of produced entanglement can be developed by increasing the mechanical frequency. Also, maximum of success probability of atoms (1,8) is increased by decreasing the optomechanical coupling strength to the field modes in most cases.
