  Using M-theory compactification, we develop a three factor separation for the
scalar submanifold of N=2 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.
