论文摘要
在没有驾驶场的情况下，在耗散浴中单个量子线的相位同步。使用Husimi $ Q $功能，我们表明，相位偏好仅在非马克维亚进化期间长期存在，并具有有限的失调。由于信息回流表示非马克维亚性是量子同步的资源，因此发生这种情况。为了量化同步，我们使用移动的相分布及其最大值。从移位相分布的最大值中，我们观察到量子同步的特征{\ it viz} arnold舌头。在我们的情况下，同步区域不在舌头区域，而舌头内部的区域则是干燥的区域。这与文献中的结果相反，在文献中同步在舌区域内。
The phase synchronization of a single qubit in a dissipative bath in the absence of driving field is demonstrated. Using the Husimi $Q$-function we show that the phase preference is present in the long time limit only during non-Markovian evolution with a finite detuning. This happens due to the information backflow signifying that non-Markovianity is a resource for quantum synchronization. To quantify synchronization we use the shifted phase distribution as well as its maximal value. From the maximal value of the shifted phase distribution we observe the signatures of quantum synchronization {\it viz} the Arnold tongue. In our case the region ofsynchronization is outside the tongue region and the region inside the tongue is the desynchronized region. This is in contrast to the results in the literature, where the synchronization is within the tongue region.
