If two identical emitters are coupled to a common reservoir, entanglement can be generated during the decay process. When using Bell's inequality to examine the non-locality, however, it is possible that the bound cannot be violated in some cases. Here, we propose to use the steering inequality to examine the non-locality induced by a common reservoir. Compared with the Bell inequality, we find that the steering inequality has a better tolerance for examining non-locality. In view of the dynamic nature of the entangling process, we also propose to observe the quantum coherent dynamics by using the Leggett-Garg inequalities. We also suggest a feasible scheme, which consists of two quantum dots coupled to nanowire surface plasmons, for possible experimental realization.
如果两个相同的发射器耦合到一个公共储层中，则在衰减过程中可以产生纠缠。然而，当使用贝尔不等式来检验非局域性时，在某些情况下，这种约束可能无法违反。在这里，我们建议使用转向不等式来检验由公共储层引起的非局域性。与贝尔不等式相比，我们发现转向不等式在检验非局域性方面具有更好的容忍度。鉴于纠缠过程的动态性质，我们还建议使用莱格特-加尔格不等式来观察量子相干动力学。我们还提出了一种可行的方案，该方案由两个量子点与纳米线表面等离激元耦合组成，用于可能的实验实现。
