Reply to Comment on "Quantum dense key distribution"
I. P. Degiovanni, I. Ruo Berchera, S. Castelletto +4
In this Reply we propose a modified security proof of the Quantum Dense Key Distribution protocol detecting also the eavesdropping attack proposed by Wojcik in his Comment.

Quantum dense key distribution
I. P. Degiovanni, I. Ruo Berchera, S. Castelletto +4
This paper proposes a new protocol for quantum dense key distribution. This protocol embeds the benefits of a quantum dense coding and a quantum key distribution and is able to gen…

Experimental Eavesdropping Attack against Ekert's Protocol based on Wigner's Inequality
F. A. Bovino, A. M. Colla, G. Castagnoli +3
We experimentally implemented an eavesdropping attack against the Ekert protocol for quantum key distribution based on the Wigner inequality. We demonstrate a serious lack of secur…
