Quantum Suicide in Many-Worlds Implies P=NP
Veronika Baumann, Alberto Rolandi
In this paper we propose a totally serious algorithm to solve NP problems in polynomial time provided one is willing to wager the fate of all observers in the universe on the many-…
Time delocalization and causality across temporal quantum reference frames
Veronika Baumann, Maximilian P. E. Lock
In relational quantum dynamics, evolution emerges via the correlations between some system of interest and a clock system, which plays the role of a temporal reference frame. Their…
No quantum advantage for violating fixed-order inequalities?
Veronika Baumann, Ãmin Baumeler, Eleftherios-Ermis Tselentis
In standard quantum theory, the causal relations between operations are fixed. One can relax this notion by allowing for dynamical arrangements, where operations may influence the…
Emergence of Classicality in Wigner's Friend Scenarios
Tom Rivlin, Sophie Engineer, Veronika Baumann
The Wigner's Friend (WF) thought experiment concerns quantum measurements by a 'superobserver' of an observer measuring a quantum system. Variations on the setup and its extended v…
