Adlam's Frame: comment on "Wigner's Frame"

Andrea Di Biagio, Anne-Catherine de la Hamette

Recent no-go theorems based on extended Wigner's Friend scenarios (EWFS) reveal a deep tension between the universal validity of quantum theory and local friendliness (LF), the con…

Observer-Dependent Entropy and Diagonal Rényi Invariants in Quantum Reference Frames

Anne-Catherine de la Hamette

Quantum reference frames provide a relational description of multipartite quantum systems in which physical states and observables are defined relative to quantum observers. Yet di…

Superposed quantum evolutions across chaotic and regular regimes

Amit Anand, Anne-Catherine de la Hamette, Robert Mann +1

While the superposition of quantum evolutions is known to produce interference effects, the interference between evolutions with regular and chaotic classical limits remains largel…

Accessibility of Global Properties from Internal Quantum Reference Frame Perspectives

Anne-Catherine de la Hamette, Viktoria Kabel, Časlav Brukner

A fundamental question in the field of quantum reference frames concerns what global properties of a system can be determined by observers operating entirely from within that syste…

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…
