Construction of channels which in every dimension anti-degrade the depolarizing channel

Shayan Roofeh, Vahid Karimipour

We consider the depolarizing channel in $d$ dimension defined as $D_{x} (ρ) = (1 - x) ρ + x tr (ρ) \frac{I}{d}$ , and explicitly find a quantum channel $N_{x}$ which anti-degra…

Capacities of a two-parameter family of noisy Werner-Holevo channels

Shayan Roofeh, Vahid Karimipour

In $d = 2 j + 1$ dimensions, the Landau-Streater quantum channel is defined on the basis of spin $j$ representation of the $s u (2)$ algebra. Only for $j = 1$ , this channel is equivalent to…
