On quantum channels and operations preserving finiteness of the von Neumann entropy
M. E. Shirokov, A. V. Bulinski
We describe the class (semigroup) of quantum channels mapping states with finite entropy into states with finite entropy. We show, in particular, that this class is naturally decom…

Lower bounds on distances between a given quantum channel and certain classes of channels
M. E. Shirokov, A. V. Bulinski
The tight, in a sense, lower estimates of diamond-norm distance from a given quantum channel to the sets of degradable, antidegradable and entanglement-breaking channels are obtain…
