We study the entanglement dynamics of two cavities interacting with independent reservoirs. Expectedly, as the cavity entanglement is depleted, it is transferred to the reservoir degrees of freedom. We find also that when the cavity entanglement suddenly disappears, the reservoir entanglement suddenly and necessarily appears. Surprisingly, we show that this entanglement sudden birth can manifest before, simultaneously, or even after entanglement sudden death. Finally, we present an explanatory study of other entanglement partitions and of higher dimensional systems.
我们研究了两个与独立库相互作用的腔的纠缠动力学。不出所料，随着腔纠缠的耗尽，它被转移到库的自由度上。我们还发现，当腔纠缠突然消失时，库纠缠会突然且必然地出现。令人惊讶的是，我们表明这种纠缠的突然产生可以在纠缠突然死亡之前、同时甚至之后表现出来。最后，我们对其他纠缠划分和高维系统进行了解释性研究。
