Quantum entropy under spontaneously generated coherence (SGC) was modeled and studied in a double quantum dot (DQD) structure. This system becomes after including the wetting layer (WL) as a ladder-plus-Y- system. The results show that the high probe field under high SGC can give good entanglement between states of the DQD system. Under the high SGC component, the optical pump was more efficient than the probe signal in increasing entanglement. The application of optical fields into WL reduces quantum entropy.

使用自发相干性的梯形加 Y 双量子点系统中的量子熵

在双量子点 (DQD) 结构中对自发相干 (SGC) 下的量子熵进行建模和研究。在将润湿层 (WL) 作为梯形加 Y 系统包括在内后，该系统就变成了。结果表明，高 SGC 下的高探测场可以在 DQD 系统的状态之间提供良好的纠缠。在高 SGC 分量下，光泵在增加纠缠方面比探针信号更有效。将光场应用于 WL 会降低量子熵。
