We develop a systematic method of solving two noninteracting Jaynes–Cummings models by using the dressed state formalism in Hilbert space HAB(2⊗2). It is shown that such model, called Double Jaynes–Cummings model (D-JCM), can be exactly solved if we take the initial bare state as the linear superposition of two Bell states. The collapse and revival oscillation, which is the standard trait of typical Jaynes–Cummings model, can be recovered if we make measurement at each local sites. Some consequence of the entanglement-induced dressing is discussed.
