Abstract

What happened to causality? This is the notion with which we understand nature: some event A causes another event B. According to general relativity, such relations are only feasible through a spacetime, in that it has to allow information to travel from A to B, and spacetimes are dynamical—they are shaped by nearby massive objects. At first sight, it seems that quantum mechanics is consistent with causality: something that happened in a quantum system at point A (say preparation) can be the cause of what happens at a later point B (say measurement). But what happens when we create a superposition of such scenarios?
