| contents | 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. |
