Remarks on the (1+1)-Matrix-Branes, qubit theory and non-compact Hopf maps

Abstract

We discuss different aspects of a possible link between the (1+1)-matrix-brane system with qubit theory and non-compact Hopf maps. In these scenarios, the (2+2)-signature plays an important role. We argue that such links may shed some light on the (2+2)-dimensional sector of a (2+10)-dimensional target background.
