我们分析研究了两个强驱动原子之间的经典和量子关联的动力学，每个原子都被困在一个耗散腔中。结果表明，存在一个有限的时间间隔，在此期间，最初在X型态制备的量子不和谐不被腔的衰变破坏。从经典关联到量子不协调的突变对初态参数、腔衰减速率和腔模驱动场失谐量都很敏感。有趣的是，我们发现，过渡时间可以显着延长，通过增加失谐的程度。
We investigate analytically the dynamics of classical and quantum correlations between two strongly driven atoms, each of which is trapped inside a dissipative cavity. It is found that there exists a finite time interval during which the quantum discord initially prepared in the X-type states is not destroyed by the decay of the cavities. The sudden transition between classical correlation and quantum discord is sensitive to the initial-state parameter, the cavity decay rate, and the cavity mode-driving field detuning. Interestingly, we show that the transition time can be prolonged significantly by increasing the degree of the detuning.
