In this talk we describe our recent work on discrete quantum theory based on
Galois fields. In particular, we discuss how discrete quantum theory sheds new
light on the foundations of quantum theory and we review an explicit model of
super-quantum correlations we have constructed in this context. We also discuss
the larger questions of the origins and foundations of quantum theory, as well
as the relevance of super-quantum theory for the quantum theory of gravity.Comment: 22 pages LaTeX. Uses ws-procs975x65.cls. Contribution to the
