From minimal informationally complete measurements to orthocentric simplices and back again
Piotr Bereza, Wojciech SÅomczyÅski, Anna Szymusiak
The reconstruction of unknown quantum states via minimal informationally complete measurements (MICs) is a cornerstone of quantum tomography. Although the statistical properties of…

Beyond morphophoricity: -tight IC measurements in geometric generalised probabilistic theories
Anna Szymusiak
The analysed in this paper new class of -tight IC measurements contains both morphophoric measurements, preserving the geometry of the states space, and tight IC measurements, i…

Can QBism exist without Q? Morphophoric measurements in generalised probabilistic theories
Anna Szymusiak, Wojciech SÅomczyÅski
In a Generalised Probabilistic Theory (GPT) equipped additionally with some extra geometric structure we define the morphophoric measurements as those for which the measurement map…
