On strong superadditivity for a class of quantum channels
Grigori Amosov
Given a quantum channel in a Hilbert space put , where , the minimum is taken…
Mathematical formulae of the all-interval tone-semitone series and the quart modes
Grigori G. Amosov, Sergei V. Golubkov
Using the residue class rings we analyze the structure of sequences of musical intervals for the all-interval tone-semitone series and the quart modes as well. The relations we sta…
On the additivity conjecture for the Weyl channels being covariant with respect to the maximum commutative group of unitaries
Grigori Amosov
Some new examples of quantum channels for which the infimum of the output entropy is additive under taking a tensor product of channels are given.
On Weyl channels being covariant with respect to the maximum commutative group of unitaries
G. G. Amosov
We investigate the Weyl channels being covariant with respect to the maximum commutative group of unitary operators. This class includes the quantum depolarizing channel and the "t…
