From minimal informationally complete measurements to orthocentric simplices and back again
Piotr Bereza, Wojciech Słomczyński, 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…

Morphophoric POVMs, generalised qplexes, and 2-designs
Wojciech Słomczyński, Anna Szymusiak
We study the class of quantum measurements with the property that the image of the set of quantum states under the measurement map transforming states into probability distribution…
