Paper Abstract

One-way quantum channels play a fundamental role in the security of the communication between two distant parties, in particular within the frame of "quantum key distribution". Nevertheless quite recently it has been introduced the possibility of using two-way quantum channels for the same purpose. Although the first attempts in this direction did not feature any particular advantage with respect to the one-way counterpart some recent results obtained by our group suggest that this new class of protocols provides higher thresholds of security.
