Improving classical capacity of qubit dynamical maps through stationary state manipulation
Katarzyna Siudzińska
We analyze the evolution of Holevo and entanglement-assisted classical capacities for a special class of phase-covariant channels. In particular, we show that these capacities can…

Enhancing phase-covariant channel performance with non-unitality
Katarzyna Siudzińska, Michał Studziński
We analyze quantum communication properties of phase-covariant channels depending on their degree of non-unitality. In particular, we derive analytical formulas for minimal and max…

Geometry of phase-covariant qubit channels
Katarzyna Siudzińska
We analyze the geometry on the space of non-unital phase-covariant qubit maps. Using the corresponding Choi-Jamiołkowski states, we derive the Hilbert-Schmidt line and volume eleme…
