On classical capacity of Weyl channels
TL;DR: In this paper, the additivity of minimal output entropy for the Weyl channel obtained by the deformation of a q-c Weyl Channel was proved for the case where the channel was obtained by a Weyl deformation, and the classical capacity of channel was calculated.
Remark on the additivity conjecture for a quantum depolarizing channel
TL;DR: In this article, the additivity conjecture holds for a quantum depolarizing channel generated by unitary representations of a discrete group, and it is shown that the additive property of the relative entropy holds for the channel.
On Weyl channels being covariant with respect to the maximum commutative group of unitaries
TL;DR: In this article, it was shown that the Weyl channels are covariant with respect to the maximum commutative group of unitary operators, including the two-Pauli channels.
On the Multiplicativity Hypothesis for Quantum Communication Channels
TL;DR: In this paper, a formulation of the multiplicativity hypothesis for quantum communication channels is given, the validity of which for parameter values p, arbitrarily close to 1, implies a positive solution of the fundamental additivity problem for channel capacity in quantum information theory.
On the information completeness of quantum tomograms
TL;DR: In this article, the authors address the problem of information completeness of quantum measurements in connection to quantum state tomography and with particular concern to quantum symplectic tomography, and introduce a measure of information incompleteness and apply it to symplectic quantum tomograms.
