  The exact solution of the system consisted from two or three q-bits doped in
coupled cavities is discussed. The problem of indistinguishable between the
excited radiators and photons is analyzed using the intrinsic symmetry of the
system. It is demonstrated that the solution is drastically simplified when the
radiators and photons are considered as a new polariton excitations. The exact
solution of Schrodinger equation is obtained for single and two excitations in
each cavity taking into consideration the indistinguishable principle. This
approach opens new possibilities in the interpretation of quantum entangled
states in comparison with the traditional distinctive situation (see for
example [1,2]) due to the decreasing of the number of degrees of freedoms in
the system. Considering that the energies of coupling between the radiators and
photons is larger than the coupling with external vacuum field, we have found
the master equation for the dumping of collective excitations of the system of
coupled radiators through the cavity fields. The time-dependence of population
for new dressed quasi-levels of energy is obtained solving analytically and
numerically the master equation.
