Abstract

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\varphi-synchronization under which the pairs of variables have the same amplitude and possess the same φ\varphi phase shift. Naturally, quantum synchronization and quantum anti-synchronization become special cases of quantum φ\varphi-synchronization. Their relations and differences are also discussed. To illustrate these theories, we investigate the quantum φ\varphi-synchronization and quantum phase synchronization phenomena of two coupled optomechanical systems with periodic modulation and show that quantum φ\varphi-synchronization is more general as a measure of synchronization. We also show the phenomenon of quantum anti-synchronization when φ=π\varphi=\pi.
