Summary: In the paper [the author, Int. J. Theor. Phys. 47, No. 10, 2754–2782 (2008; Zbl 1160.81398)], generalized projective geometries have been proposed as a framework for a geometric formulation of Quantum Theory. In the present note, we refine this proposition by discussing further structural features of Quantum Theory: the link with associative involutive algebras \(\mathbb A\) and with Jordan-Lie and Lie-Jordan algebras. The associated geometries are (Hermitian) projective lines over \(\mathbb A\); their axiomatic definition and theory will be given in subsequent work [the author and M. Kinyon, in preparation].
