%X The semi-classical theory of the interaction between light and matter was applied to the study of the interaction of ultra-short pulse with the two two-level system.A comparison was made between the independent double path-ways(IDPW) and the coherent double path-ways(CDPW) driven in different ways.It is suggested that compared with single qubit,the two-qubits shows a higher property of coherence when interacted with the ultra-short pulse.This property of coherence is related to the initial state of the system,the detuning,and the driving path-ways.And,it is demonstrated that with the presented model quantum state operation can be made through the modulation of the pulse area.
