“…В настоящее время динамика перепутывания кубитов, индуцированного полями резонаторов, исследована для большого числа различных многокубитных моделей типа Джейнса−Каммингса (см. ссылки в [6][7][8][9][10][11]). Использование перепутанных состояний для квантовых вычислений и коммуникаций предполагает необходимость выбора надлежащих мер количественной оценки степени перепутывания кубитов.…”

We found the exact solution for a model consisting of two dipole-coupled qubits, one of which is an isolated, and the other interacts with the thermal mode of a cavity with the Kerr medium. The results showed that Kerr nonlinearity may greatly enhance the degree of entanglement induced by a thermal field both for separable and entangled initial states of qubits. We also showed the possibility of the disappearance of the sudden death of entanglement for a model with a Kerr nonlinearity..

“…This bipartite system can theoretically be described by the Jaynes-Cummings model (J-CM) [31]. Various generalizations of J-CM have lately been introduced and examined [32][33][34][35][36][37]. Based on the above aforementioned, we present in this manuscript the examination of physical phenomena and illustrate the convenable conditions for different applications of quantum technology.…”

In this manuscript, we introduce a quantum physical model consisting of two-atom system that interact with a quantized field initially prepared in the thermal spin states (TSSs). We study the effect of the main parameters of the model on the dynamical behavior atom–atom coherence, atoms-field entanglement, atom–atom entanglement and classical correlation. We show how the quantumness measures can be influenced by the spin number and thermal noise in the absence and presence of time-dependent coupling effect. We obtain that, despite the destructive influence of thermal noise, a considerable amount of coherence, entanglement and classical correlation still remain during the time evolution according the values of spin number. The results also show that the TSSs can offer the advantage of generating the maximal amount of coherence, entanglement and classical correlation during the dynamics.

“…In that paper, the authors also provided the limit for obtaining the state with maximum value of von Neumann entropy. The dynamics of quantum entanglement for a double JCM was examined in [ 7 , 8 , 9 , 10 , 11 , 12 , 13 ]. The entanglement phenomenon of sudden death in the double JCM was observed [ 14 ].…”

We developed a quantum scheme of two atoms (TAs) and field initially in a negative binomial state (NBS). We displayed and discussed the physical implications of the obtained results in terms of the physical parameters of the model. By considering that the TAs were initially prepared in a maximally entangled state, and that the single-mode field was in the NBS, the dynamics of quantum phenomena such TAs–field entanglement, TAs entanglement, and parameter estimation were examined. We found that the quantum quantifiers exhibited randomly quasi-periodic and periodic oscillations that depended on the success probability, photon number transition, and the intensity-dependent coupling effect. Furthermore, we analyzed the connection between the dynamical behavior of the quantifiers. This system can be compared with some other ones that are being discussed in the literature, in order to realize the quantum entanglement, and to control the precision of the parameter estimation.
