Linking Edge Modes and Geometrical Clocks in Linearized Gravity
Kristina Giesel, Viktoria Kabel, Wolfgang Wieland
Reference frames are crucial for describing local observers in general relativity. In quantum gravity, different proposals exist for how to treat reference frames. There are models…
Knot invariants and indefinite causal order
Samuel Fedida, Anne-Catherine de la Hamette, Viktoria Kabel +1
We explore indefinite causal order between events in the context of quasiclassical spacetimes in superposition. We introduce several new quantifiers to measure the degree of indefi…
What an event is not: unravelling the identity of events in quantum theory and gravity
Anne-Catherine de la Hamette, Viktoria Kabel, Časlav Brukner
We explore the notion of events at the intersection between quantum physics and gravity, inspired by recent research on superpositions of semiclassical spacetimes. By going through…
Identification is Pointless: Quantum Coordinates, Localisation of Events, and the Quantum Hole Argument
Viktoria Kabel, Anne-Catherine de la Hamette, Luca Apadula +4
The study of quantum reference frames (QRFs) is motivated by the idea of taking into account the quantum properties of the reference frames used, explicitly or implicitly, in our d…
