Abstract
We propose a framework for temporal quantum theories for the purpose of describing states and observables associated with extended regions of space-time quantum mechanically. The proposal is motivated by Isham’s history theories. We discuss its relation to Isham’s history theories and to standard quantum mechanics. We generalize the Isham-Linden information entropy to the present context.
