  Using graph theory based on Adinkras, we consider once again the study of
extremal black branes in the framework of quantum information. More precisely,
we propose a one to one correspondence between qubit systems, Adinkras and
certain extremal black branes obtained from type IIA superstring compactified
on T^n. We accordingly interpret the real Hodge diagram of T^n as the geometry
of a class of Adinkras formed by 2^n bosonic nodes representing n qubits. In
this graphic representation, each node encodes information on the qubit quantum
states and the charges of the extremal black branes built on T^n. The
correspondence is generalized to n superqubits associated with odd and even
geometries on the real supermanifold T^{n|n}. Using a combinatorial
computation, general expressions describing the number of the bosonic and the
fermionic states are obtained.
