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.
