论文摘要
通过使用符号几何形状来解决三个非共振超耦合振荡器的米尔本动力学。我们查看虚拟激发的米尔本动态及其如何影响成对的纠缠。发现激发和纠缠的动力学会在时间，物理参数和破坏率上经历相似的曲线。此外，我们表明激发的灭绝需要分离性，这证明了纠缠与虚拟激发之间的层次结构。此外，我们分析了物理参数对这三个两部分之间虚拟激发的重新分布的影响。结果，我们表明了对量子不和谐的激发一夫一妻制的侵犯。这意味着激发可以被视为超出纠缠的量子相关的特征。此外，我们强调我们的处理可用于在实际情况下（具有抗碳）对耦合的量子电路进行建模。
The Milburn dynamics of three nonresonant ultra-strongly coupled oscillators are resolved by using symplectic geometry. We look at the Milburn dynamics of virtual excitations and how they affect pairwise entanglement. It is found that the dynamics of excitations and entanglement experience similar profiles against time, physical parameters, and decoherence rate. Furthermore, we show that the extinction of excitations entails separability, which demonstrates the hierarchy between entanglement and virtual excitations. Additionally, we analyze the effects of physical parameters on the redistribution of virtual excitations among the three bi-partitions. As a result, we show the violation of the monogamy of excitations as in quantum discord. This implies that excitations can be considered as signatures of quantum correlations beyond entanglement. Besides, we emphasize that our treatment can be used to model coupled quantum circuits in real situations (with decoherence).
