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…

Certifying high-dimensional quantum channels
Sophie Engineer, Suraj Goel, Sophie Egelhaaf +9
The use of high-dimensional systems for quantum communication opens interesting perspectives, such as increased information capacity and noise resilience. In this context, it is cr…

Equilibration of objective observables in a dynamical model of quantum measurements
Sophie Engineer, Tom Rivlin, Sabine Wollmann +2
The challenge of understanding quantum measurement persists as a fundamental issue in modern physics. Particularly, the abrupt and energy-non-conserving collapse of the wave functi…
