On the Black-Hole/Qubit Correspondence

TL;DR

This paper explores a deep connection between quantum entanglement classifications of multiple qubits and the properties of extremal black holes in various supergravity theories, revealing a novel correspondence between quantum information and gravitational physics.

Contribution

It generalizes the black-hole/qubit correspondence to complex four-way entanglement of eight qubits and links it to black holes in N=8 and N=2 supergravity theories.

Findings

Entanglement classification relates to black hole solutions in supergravity.

Extended the correspondence to eight-qubit entanglement.

Provides a unified framework connecting quantum information and gravity.

Abstract

The entanglement classification of four qubits is related to the extremal black holes of the 4-dimensional STU model via a time-like reduction to three dimensions. This correspondence is generalised to the entanglement classification of a very special four-way entanglement of eight qubits and the black holes of the maximally supersymmetric N = 8 and exceptional magic N = 2 supergravity theories.
