On the convergence of output sets of quantum channels
Benoit Collins, Motohisa Fukuda, Ion Nechita
We study the asymptotic behavior of the output states of sequences of quantum channels. Under a natural assumption, we show that the output set converges to a compact convex set, c…

Revisiting additivity violation of quantum channels
Motohisa Fukuda
We prove additivity violation of minimum output entropy of quantum channels by straightforward application of ε-net argument and Lévy's lemma. The additivity conjecture was disprov…
