All classes of informationally complete symmetric measurements in finite dimensions
Katarzyna Siudzińska
A broad class of informationally complete symmetric measurements is introduced. It can be understood as a common generalization of symmetric, informationally complete POVMs and mut…
Entanglement witnesses from mutually unbiased measurements
Katarzyna Siudzińska, Dariusz Chruściński
A new family of positive, trace-preserving maps is introduced. It is defined using the mutually unbiased measurements, which generalize the notion of mutual unbiasedness of orthono…
Engineering classical capacity of generalized Pauli channels with admissible memory kernels
Katarzyna Siudzińska, Arpan Das, Anindita Bera
We analyze the classical capacity of the generalized Pauli channels generated via the memory kernel master equations. For suitable engineering of the kernel parameters, the evoluti…
Interpolating between positive and completely positive maps: a new hierarchy of entangled states
Katarzyna Siudzińska, Sagnik Chakraborty, Dariusz Chruściński
A new class of positive maps is introduced. It interpolates between positive and completely positive maps. It is shown that this class gives rise to a new characterization of entan…
Non-Markovianity criteria for mixtures of noninvertible Pauli dynamical maps
Katarzyna Siudzińska
We analyze the connections between the non-Markovianity degree of the most general phase-damping qubit maps and their legitimate mixtures. Using the results for image non-increasin…
Markovian semigroup from mixing non-invertible dynamical maps
Katarzyna Siudzińska
We analyze the convex combinations of non-invertible generalized Pauli dynamical maps. By manipulating the mixing parameters, one can produce a channel with shifted singularities,…
