论文摘要
我们研究量子系统如何从重力场的量子自由度中收获纠缠。具体而言，我们详细描述了非浮动量量子系统与线性化量子重力的相互作用，并探讨了在这种情况下，两个空格类似的探针如何从重力场中收获纠缠。我们为现实探针的收获纠缠提供了估计，这将来可以在实验上相关，因为纠缠收集实验可以为存在量子的重力自由度的存在提供证据。
We study how quantum systems can harvest entanglement from the quantum degrees of freedom of the gravitational field. Concretely, we describe in detail the interaction of non-relativistic quantum systems with linearized quantum gravity, and explore how two spacelike separated probes can harvest entanglement from the gravitational field in this context. We provide estimates for the harvested entanglement for realistic probes which can be experimentally relevant in the future, since entanglement harvesting experiments can provide evidence for the existence of quantum degrees of freedom of gravity.
