Such states could arise for example, from a source mass in a superposition of spatial configurations. In this paper we introduce a framework for describing such \"quantum superpositions of spacetime states.\" We introduce the notion of the relativity of spacetime superpositions, demonstrating that for states in which the superposed amplitudes differ by a coordinate transformation, it is always possible to re-express the scenario in terms of dynamics ","authors_text":"Joshua Foo, Magdalena Zych, Robert B.
