Continuity inequalities for sandwiched Rényi and Tsallis conditional entropies with application to the channel entropy continuity
Anna Vershynina
For the sandwiched Rényi entropy the conditional entropy can be defined two ways: . In the limiting case, $…

Dynamical Coherence Measures
Anna Vershynina
We present three measures of the dynamical coherence of channels, which are the generalization of several previous results. The measures are based on the generalized distance funct…

Coherence as entropy increment for Tsallis and Renyi entropies
Anna Vershynina
Relative entropy of coherence can be written as an entropy difference of the original state and the incoherent state closest to it when measured by relative entropy. The natural qu…
