On the entropy gain under the action of amplitude damping channel on qutrit
Grigori G. Amosov, Andrey I. Dnestryan
After realising qutrit in the form of bipartite system we estimate from below the entropy gain under the action of the amplitude damping channel.

On tomographic representation on the plane of the space of Schwartz operators and its dual
G. G. Amosov
It is shown that the set of optical quantum tomograms can be provided with the topology of Frechet space. In such a case the conjugate space will consist of symbols of quantum obse…

Tomographic portrait of quantum channels
G. G. Amosov, S. Mancini, V. I. Man'ko
We formulate the notion of quantum channels in the framework of quantum tomography and address there the issue of whether such maps can be regarded as classical stochastic maps. In…
