Equiangular weighted frames and conical 2-designs with unequal traces
Katarzyna Siudzińska
Conical 2-designs are families of positive operators possessing crucial symmetry properties that allow them to efficiently characterize important quantum measures. However, little…

Equivalence relations between conical 2-designs and mutually unbiased generalized equiangular tight frames
Katarzyna Siudzińska
Quantum measurements play a fundamental role in quantum information. Therefore, increasing efforts are being made to construct symmetric measurement operators for qudit systems. A…

Measures from conical 2-designs depend only on two constants
Katarzyna Siudzińska
Quantum measurements are important tools in quantum information, represented by positive, operator-valued measures. A wide class of symmetric measurements is given via generalized…
