We consider a model consisting of three identical qubits, one of which is in a free state and the other two are locked in an ideal resonator with a Kerr medium and interact resonantly with a selected mode of this resonator. The degree of coincidence is calculated for two genuine entangled W-type states and the GHZ-type state and the thermal state of the resonator field. The influence of the resonator thermal noise intensity and Kerr nonlinearity on the degree of coincidence of qubit states is investigated. It is shown that the thermal field of the resonator does not completely destroy the initial entangled states of the qubits, even for relatively high intensities of thermal noise of the resonator. It is also established that the Kerr nonlinearity of the resonator leads to stabilization of the initial entanglement of qubits. Keywords: qubits, genuine entangled W- and GHZ-type states, thermal field, Kerr nonlinearity, degree of coincidence of qubit states.
