Analysis of complete positivity conditions for quantum qutrit channels
A. Checinska, K. Wodkiewicz
We present an analysis of complete positivity (CP) constraints on qutrit quantum channels that have a form of affine transformations of generalized Bloch vector. For diagonal (damp…

Depolarization channels with zero-bandwidth noises
Andrzej Dragan, Krzysztow Wódkiewicz
A simple model describing depolarization channels with zero-bandwidth environment is presented and exactly solved. The environment is modelled by Lorentzian, telegraphic and Gaussi…

Classical and quantum Malus' law
K. Wodkiewicz
The classical and the quantum Malus' Laws for light and spin are discussed. It is shown that for spin-1/2, the quantum Malus' Law is equivalent in form to the classical Malus' Law…
