Unitary evaporation involving quantum gravitational degrees of freedom must entail a new type of nonlocality, possibly beyond-quantum, but need not imply the possibility of causal loops.
“We argue that whereas the unitary evaporation involving quantum gravitational degrees of freedom must entail a new type of nonlocality-possibly beyond-quantum [33,34]-, it need not imply the possibility of causal loops.”

There exist probabilistic theories exhibiting a beyond-quantum form of nonlocality while not allowing any superluminal transfer of information.
“In fact, there exist probabilistic theories exhibiting a beyond-quantum form of nonlocality, while not allowing for any superluminal transfer of information [33].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
