Abstract

In this work, we analyze the effects of quantum synchronization \({\varvec{S}}_{\varvec{q}}\) and \(\varvec{\phi }\) synchronization \({\varvec{S}}_{\varvec{q}}^{\varvec{\phi }}\) in a hybrid optomechanical system composing a representative coupled optomechanical component and a two-level atom. Although an atom may induce some perturbations to synchronization, good quantum synchronization and quantum \(\varvec{\phi }\) synchronization can also be achieved in the hybrid optomechanical system. Moreover, we investigate the responses of the two synchronization measures on different periodic modulations in the presence and absence of an atom respectively. In addition, the effects of Kerr nonlinearity on quantum synchronization are also investigated. Our results can provide a theoretical foundation for quantum synchronization in hybrid optomechanical systems and realize some valuable applications in quantum information processing and quantum networks.

双能级原子混合光力学系统中的量子同步与\(\phi \)同步

在这项工作中，我们分析了量子同步\({\varvec{S}}_{\varvec{q}}\)和\(\varvec{\phi }\)同步\({\varvec{S}}_{\varvec{q}}^{\varvec{\phi }}\)在一个由具有代表性的耦合光力学元件和两能级原子组成的混合光力学系统中的影响。虽然原子可能会引起一些微扰，但在混合光力学系统中也可以实现良好的量子同步和量子\(\varvec{\phi }\)同步。此外，我们还分别研究了两种同步措施在不同周期调制下原子存在和不存在时的响应。此外，还研究了克尔非线性对量子同步的影响。我们的研究结果可以为混合光力学系统中的量子同步提供理论基础，并在量子信息处理和量子网络中实现一些有价值的应用。

期刊介绍： International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
