In this paper, an analytical solution of the two-qubit Rabi model for the general case is presented.
Furthermore, a comparison between the information entropies and the Von Neumann entropy S(Ï A ) is given for
some special values of the qubit-photon coupling constants for the two qubits and the detuning parameters. It
is demonstrated that oscillations of the occupation probabilities Ï11 , Ï22 , Ï33 and Ï44 are equivalent to the case of
the spontaneous emission. The occupation probability Ï11 reaches the case of sudden death, when the detuning
parameter ∆2 equals zero.
