Published

Author(s)

Stefania Castelletto, Ivo P. Degiovanni, M L. Rastello

Abstract

In this letter we discuss the insecurity with present implementations of the Ekert protocol for quantum-key distribution based on the Wigner Inequality. We propose a modified version of this inequality which guarantees safe quantum-key distribution.
