Signatures of causality and determinism in a quantum theory of events

By representing an event as the joint state of a detector-timer couple that interact with system, we recover familiar tensor product structure, used to describe spatially separated systems, in context timelike events. Furthermore, this approach, extend superposition principle moment occurrence We then outline quantum signatures causality manifest through coherence detector and correlation functions time operators. Finally, expand scope information theoretic measures discrimination content, commonly characterize events spacetime. For causally connected events, illustrate deterministic relationship between (akin entangled physical systems) where observing previous (one subsystem), enables us delineate later (the other subsystem).
