Phase-covariant mixtures of non-unital qubit maps
Katarzyna Siudzińska
We analyze convex combinations of non-unital qubit maps that are phase-covariant. In particular, we consider the behavior of maps that combine amplitude damping, inverse amplitude…

Indecomposable entanglement witnesses from symmetric measurements
Katarzyna Siudzińska
We propose a family of positive maps constructed from a recently introduced class of symmetric measurements. These maps are used to define entanglement witnesses, which include oth…
