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…
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…
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…
Continuity bounds on observational entropy and measured relative entropies
Joseph Schindler, Andreas Winter
We derive a measurement-independent asymptotic continuity bound on the observational entropy for general POVM measurements, making essential use of its property of bounded concavit…
