Qubits from black holes in M-theory on K3 surface.

Using M-theory compactification, we develop a three-factor separation for the scalar submanifold of seven-dimensional supergravity associated with 2-cycles of the K3 surface. Concretely, we give an interplay between the three-scalar submanifold factors and the extremal black holes obtained from M2-branes wrapping such 2-cycles. Then, we show that the corresponding black hole charges are linked to one, two and four qubit systems. [ABSTRACT FROM AUTHOR]
