On the basis of the exact solution of the considered model, the Peres-Horodetskii entanglement parameter (negativity) for qubits has been found. Numerical simulation of the negativity for various model parameters has been carried out. It has been shown that the interaction of qubits with the thermal field of the resonator can lead to their entanglement. It ha been established that the detuning and dipole-dipole interaction of qubits can be used to manipulate and control the degree of their entanglement.</p>qubitsdetuningdipole-dipole interactionthermal fieldqubit-qubit entanglemententanglement controlкубитырасстройкадиполь-дипольное взаимодействиетепловое полеперепутывание кубитовуправление перепутыванием
