# Entanglement wedge reconstruction Entanglement wedge reconstruction is the statement that everything in the entanglement wedge in the bulk can be constructed from data in the corresponding boundary region. ## Related - [[0146 Quantum error correction]] - [[0142 Entanglement wedge nesting]] - [[0007 RT surface]] - [[0026 Bulk reconstruction]] ## Refs - development - [[CzechKarczmarekNogueiraVanRaamsdonk2012]] - [[2014#Headrick, Hubeny, Lawrence, Rangamani]] - [[Wall2014]] - later work - [[2016#Jafferis, Lewkowycz, Maldacena, Suh]] - [[2016#Dong, Harlow, Wall]] - proves the possibility of entanglement wedge reconstruction - [[CotlerHaydenPeningtonSaltonSwingleWalter2017]] - challenges/counter examples - [[2019#Bao, Chatwin-Davies, Niehoff, Usatyuk]] ## Redundancy - there exist multiple distinct reconstructions -> redundant - best understood in terms of [[0146 Quantum error correction|quantum error correction]] ## Consistency with [[0001 AdS-CFT|AdS/CFT]] It seems contradictory that GKPW or BDHM both require knowledge beyond the entanglement wedge while entanglement wedge reconstruction says otherwise. The resolution proposed by [[GuijosaOlivasPedraza2022]] says that one needs to prescribe a IR BC, associated with an EOW brane. This procedure is called [[0375 Holographic rememorisation|holographic rememorisation]].
