We consider discrete time feedback aimed at reclaiming quantum information after a channel action. We compare Bayesian and Markovian strategies. We show that the former does not offer any advantage for qubit channels, while its superior performance can appear in higher-dimensional channels. This is witnessed by cases study for qutrit channels.

Abstract
We consider discrete time feedback aimed at reclaiming quantum information after a channel action. We compare Bayesian and Markovian strategies. We show that the former does not offer any advantage for qubit channels, while its superior performance can appear in higher-dimensional channels. This is witnessed by cases study for qutrit channels.File in questo prodotto:
