摘要：

基于A. Mari \textit{et al.} in Phys. Rev. Lett. 111，103605（2013）中，我们引入并表征了称为量子$φ$ -同步的更广义的量子同步的度量，在该量子同步下，变量对具有相同的幅度并且具有相同的$φ$相移。自然，量子同步和量子反同步成为量子$φ$ -同步的特殊情况。并讨论了它们之间的联系和区别。为了说明这些理论，我们调查的量子$φ$ -同步和量子相位同步现象的两个耦合的光机械系统的周期调制和显示，量子$φ$ -同步是更普遍的同步措施。我们还发现了当$φ=π$ .

英文摘要：

Based on the concepts of quantum synchronization and quantum phase synchronization proposed by A. Mari \textit{et al.} in Phys. Rev. Lett. 111, 103605 (2013), we introduce and characterize the measure of a more generalized quantum synchronization called quantum $φ$-synchronization under which the pairs of variables have the same amplitude and possess the same $φ$ phase shift. Naturally, quantum synchronization and quantum anti-synchronization become special cases of quantum $φ$-synchronization. Their relations and differences are also discussed. To illustrate these theories, we investigate the quantum $φ$-synchronization and quantum phase synchronization phenomena of two coupled optomechanical systems with periodic modulation and show that quantum $φ$-synchronization is more general as a measure of synchronization. We also show the phenomenon of quantum anti-synchronization when $φ=π$.
