Four-qubit entanglement from string theory

High Energy Physics - Theory 2010-09-03 v2 Quantum Physics

Abstract

We invoke the black hole/qubit correspondence to derive the classification of four-qubit entanglement. The U-duality orbits resulting from timelike reduction of string theory from D=4 to D=3 yield 31 entanglement families, which reduce to nine up to permutation of the four qubits.
