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…
Can QBism exist without Q? Morphophoric measurements in generalised probabilistic theories
Anna Szymusiak, Wojciech Słomczyński
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…
Orthogonal Projections on Hyperplanes Intertwined With Unitaries
Wojciech Słomczyński, Anna Szczepanek
Fix a point in a finite-dimensional complex vector space and consider the sequence of iterates of this point under the composition of a unitary map with the orthogonal projection o…
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…
Quantum dynamical entropy, chaotic unitaries and complex Hadamard matrices
Wojciech Słomczyński, Anna Szczepanek
We introduce two information-theoretical invariants for the projective unitary group acting on a finite-dimensional complex Hilbert space: PVM- and POVM-dynamical (quantum) entropi…
Informational power of the Hoggar SIC-POVM
Anna Szymusiak, Wojciech Słomczyński
We compute the informational power for the Hoggar SIC-POVM in dimension 8, i.e. the classical capacity of a quantum-classical channel generated by this measurement. We show that th…
