The topology of CSS (Calderbank-Shor and Steane) codes can be realized in a geometrical setting in which there is a locality condition which requires that each stabilizer involves only a bounded number of Pauli matrices. It is shown that a suitable framework is provided by the Riemannian geometry of closed smooth manifold \(M^{d}\). In this unified approach one can answer two conjectures, one in differential geometry, and the other one in quantum information. Some definitions related to the notations are missing. For instance, \(S^{2}\times S^{1}\), what is it?
