In this work we show that in the quantum setting the probabilistic behavior can be completely eliminated. We also show how to combine quantum polar encoding with superactivation-assistance in order to achieve private communication over noisy quantum relay channels. %G English %Z TC 6 %Z WG 6.2 %Z WG 6.6 %2 https://inria.hal.science/hal-01543144/document %2 https://inria.hal.science/hal-01543144/file/978-3-642-32808-4_22_Chapter.pdf %L hal-01543144 %U https://inria.hal.science/hal-01543144 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-TC6 %~ IFIP-WG6-6 %~ IFIP-WG6-2 %~ IFIP-EUNICE %~ IFIP-LNCS-7479
