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…
Coupling Efficiencies in Single Photon On-Demand Sources
Stefania Castelletto, I. P. Degiovanni, Michael Ware +1
Many quantum computation and communication schemes require, or would significantly benefit from, true sources of single photon on-demand (SPOD). Unfortunately, such sources do not…
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…
A Modified Wigner's Inequality for Secure Quantum Key Distribution
S. Castelletto, I. P. Degiovanni, M. L. Rastello
In this report we discuss the insecurity with present implementations of the Ekert protocol for quantum-key distribution based on the Wigner Inequality. We propose a modified versi…
