研究了由耦合光机系统构成的复杂网络的量子同步现象，证明了即使拓扑结构变化，未知的量子态也可以在量子网络中共享或分布.考虑一个由量子关联构成的通道，我们证明了量子同步可以在很长一段时间内维持并维持高的马尔可夫耗散水平。我们还分析了两个典型复杂网络之间的状态共享过程，结果表明，连接节点可以直接同步，但整个网络只有在满足特定同步条件时才能同步。通过对网络动力学的分析，给出了同步的解析条件。该方案为研究复杂网络中的多相互作用同步和实现有效的量子信息处理铺平了道路。
We investigate the quantum synchronization phenomenon of the complex network constituted by coupled optomechanical systems and prove that the unknown identical quantum states can be shared or distributed in the quantum network even though the topology is varying. Considering a channel constructed by quantum correlation, we show that quantum synchronization can sustain and maintain high levels in Markovian dissipation for a long time. We also analyze the state-sharing process between two typical complex networks, and the results predict that linked nodes can be directly synchronized, but the whole network will be synchronized only if some specific synchronization conditions are satisfied. Furthermore, we give the synchronization conditions analytically through analyzing network dynamics. This proposal paves the way for studying multi-interaction synchronization and achieving effective quantum information processing in a complex network.
