# Causal wedge inclusion Causal wedge inclusion states that the causal wedge must lie inside the entanglement wedge. ## Derivation / motivation - [[0219 Entanglement wedge reconstruction|entanglement wedge reconstruction]] and the fact that there exist unitary operators on the boundary whose effect in the bulk propagates causally => causal wedge inclusion - alternatively, it follows from [[0142 Entanglement wedge nesting|EWN]] ## Refs - [[Wall2012]] - [[2014#Headrick, Hubeny, Lawrence, Rangamani]]
