标题： Inflation does not create entanglement in local observables

摘要： 利用现代相对论量子信息工具，我们比较了 de Sitter 时空的宇宙学区域中 Bunch-Davies 真空中的自由、大质量纯量场与闵可夫斯基时空中相应场的纠缠性。尽管 de Sitter 场在大尺度上存储了更多的纠缠，但其空间局域化场模之间的纠缠却更少。这表明膨胀过程不会在局域可观测量之间产生纠缠。 显示英文摘要

摘要： Using modern tools of relativistic quantum information, we compare entanglement of a free, massive scalar field in the Bunch-Davies vacuum in the cosmological patch of de Sitter spacetime with that in Minkowski spacetime. There is less entanglement between spatially localized field modes in de Sitter, despite the fact that there is more entanglement stored in the field on large scales. This shows that inflation does not produce entanglement between local observables.
