论文摘要
我们研究了纠缠收集的方案，其中两个间距分离的粒子探测器从量子场提取量子相关性。具体而言，我们分析了探测器在协议中的场质量和能量缺口的作用。也许令人惊讶的是，我们发现有些制度通过减少检测器所经历的噪声来随着田间的质量而增加的纠缠行为。最后，我们研究了检测器的间隙与设置的其他参数之间最大化收获的纠缠之间的最佳关系，这表明即使在这种情况下，很小的质量也可以改善协议。
We investigate the protocol of entanglement harvesting, where two spacelike separated particle detectors extract quantum correlations from a quantum field. Specifically, we analyze the role of the mass of the field and the energy gap of the detectors in the protocol. Perhaps surprisingly, we find that there are regimes in which the entanglement harvested can increase with the mass of the field by decreasing the noise experienced by the detectors. Finally, we study the optimal relationship between the gap of the detectors and the other parameters of the setting that maximizes the entanglement harvested, showing that a small mass can improve the protocol even in this case.
