Holographic Absolutely Maximally Entangled States in Black Hole Interiors

Year: 2025

Type: article

Abstract: We argue that the special extremal slice inside an AdS black hole is dual to an absolutely maximally entangled (AME) state. We demonstrate this by confirming the n-independence of holographic nth Renyi entropies for any bipartite subsystems. Our result gives an AME state in an infinite-volume system, where the local bond dimension is set by the black hole entropy. In particular, our construction provides concrete support from the gravity side for the emergence of random structures and an infinite-dimensional Hilbert space in recent nonisometric holographic codes.
