New constructive counterexamples to additivity of minimum output Rényi p-entropy of quantum channels
Krzysztof Szczygielski, Michał Studziński
In this paper, we present new families of quantum channels for which corresponding minimum output Rényi -entropy is not additive. Our manuscript is motivated by the results of G…
Markovian theory of dynamical decoupling by periodic control
Krzysztof Szczygielski, Robert Alicki
The recently developed formalism of Markovian master equations for quantum open systems with external periodic driving is applied to the theory of dynamical decoupling by periodic…
Markovian Master Equation and Thermodynamics of Two-level System in Strong Laser Field
K. Szczygielski, D. Gelbwaser-Klimovsky, R. Alicki
The recently developed technique combining the weak coupling limit with the Floquet formalism is applied to a model of two-level atom driven by a strong laser field and weakly coup…
