A sharp version of the information paradox involves a seeming violation of the monogamy of entanglement during black hole evaporation. We construct an analogous paradox in empty anti-de Sitter space. In a local quantum field theory, Bell correlations between operators localized in mutually spacelike regions are monogamous. We show, through a controlled calculation, that this property can be violated by an order-1 factor in a theory of gravity. This example demonstrates that what appears to be a violation of the monogamy of entanglement may just be a subtle violation of locality in quantum gravity.

I thank the author for their detailed response. The changes implemented address all of my comments and requested changes satisfactorily.
While I still have reservations about the usefulness of this (interesting) argument as a toy model for the information paradox, in the revised manuscript I am satisfied that the assumptions and key steps of the argument are stated much more clearly, enabling readers to draw their own conclusions.
I therefore recommend that this submission should be published in SciPost Physics.
