摘要
We study the portion of an asymptotically Anti-de Sitter geometry's bulk where the metric can be reconstructed, given the areas of minimal two-surfaces anchored to a fixed boundary subregion. We exhibit situations in which this region can reach parametrically far outside of the entanglement wedge. If the setting is furthermore holographic, so that the bulk geometry is dual to a state in a conformal field theory (CFT), these minimal two-surface areas can be deduced from the expectation values of operators localized within the boundary subregion. This presents us with an alternative: either the reduced CFT state encodes significant information about the bulk beyond the entanglement wedge, challenging conventional intuition about holographic subregion duality, or the reduced CFT state fails to contain information about operators whose expectation values give the areas of minimal two-surfaces anchored within that subregion, challenging conventional intuition about the holographic dictionary.
