Entropic partial orderings of quantum measurements
Adam Teixidó-Bonfill, Joseph Schindler, Dominik Šafránek
We investigate four partial orderings on the space of quantum measurements (i.e on POVMs or positive operator valued measures), describing four notions of coarse/fine-ness of measu…

First Principles Numerical Demonstration of Emergent Decoherent Histories
Philipp Strasberg, Teresa E. Reinhard, Joseph Schindler
Within the histories formalism the decoherence functional is a formal tool to investigate the emergence of classicality in isolated quantum systems, yet an explicit evaluation of i…

Observational entropy with general quantum priors
Ge Bai, Dominik Šafránek, Joseph Schindler +2
Observational entropy captures both the intrinsic uncertainty of a thermodynamic state and the lack of knowledge due to coarse-graining. We demonstrate two interpretations of obser…
