Two Realizations of a Gravitational Quantum Switch

The original version of a gravitational switch has been introduced in:

arXiv:1708.00248 by Zych, Costa, Pikovski and Brukner

We introduce a new, different realization of the gravitational switch, and compare it to the original one. We discuss the structure of the new switch, and analyze it in the framework of relationalism. We will also touch upon related topics of the switch observability, timelike double slit, causality, and whether or not the spacetime manifold is observable.
