On strong superadditivity for a class of quantum channels

Grigori Amosov

Given a quantum channel $Φ$ in a Hilbert space $H$ put $H^_{Φ} (ρ) = ρ_{a v} = ρ min Σ_{j = 1}^{k} π_{j} S (Φ (ρ_{j}))$ , where $ρ_{a v} = Σ_{j = 1}^{k} π_{j} ρ_{j}$ , the minimum is taken…

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…
