Dynamics analysis of Two-level Two-qubit coupling system under the Laser pulses driver

Abstract

Abstract: The research in under the action of wave type laser pulses, detuning, coupling or jumping coefficient is large enough, a two-level coupling modes in the system of double bits and bit transition, through the analysis and numerical calculation, the method of the combination of numerical solution of the export system and describe the time evolution of the nature.By adjusting the frequency of plus pulse respectively with two cavity near the resonance occurs, and compared with non-resonant conditions such as, found that the two effects:one is the plus pulse respectively and the cavity field near resonance happens, the cavity of the bit and the modes of excitation probability approximation to the sum of 1, that can be done, system will be imprisoned in a cavity energy transfer. Another is the mismatch of coefficient is large enough, plus pulse effect on the cavity field, for example, under the condition of large detuning, pulse and the cavity field near resonance occurs, bits of excitation probability and by the pulse with perfect control and basic modes do not do.
