On the information completeness of quantum tomograms

Grigori G. Amosov, Stefano Mancini, Vladimir I. Man'ko

We address the problem of information completeness of quantum measuremets in connection to quantum state tomography and with particular concern to quantum symplectic tomography. We…

The strong superadditivity conjecture holds for the quantum depolarizing channel in any dimension

Grigori G. 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…
