We propose a protocol for deterministic communication that does not make use of entanglement. It exploits non- orthogonal states in a two-way quantum channel to attain unconditional security and high efficiency of the transmission.

Abstract
We propose a protocol for deterministic communication that does not make use of entanglement. It exploits non- orthogonal states in a two-way quantum channel to attain unconditional security and high efficiency of the transmission. We explicitly show the scheme is secure against a class of individual attacks regardless of the noise on the channel. Its experimental realization is feasible with current technology.File in questo prodotto:
