Sudden Birth versus Sudden Death of Entanglement in Multipartite Systems
Sudden Birth versus Sudden Death of Entanglement in Multipartite Systems
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 …
