  • Abstract

    By numerical optimization the parameters of eavesdropper's quantum probe are found, at which its information on a key is maximal in a wide interval of a disturbance level between legitimate users. It is shown, that the protocol with qutrits transfer is more robust against optimal incoherent attack, than the BB84 protocol, the protocol with six states and the Ekert's protocol.
