Detecting eve in communication with continuous-variable Einstein-Podolsky-Rosen correlations
We study the validity of the entanglement parameter introduced in a recent publication by Guangqiang et al. Phys. Rev. A 73 012314 (2006)] for detecting Eve, the eavesdropper. We have found that Eve can be detected using this parameter only if Alice establishes a quantum correlation between the Eins...
