Implementation Of Decoy State Protocol
Authors : Ali Sellami . Mohammed Sellami .
Abstract
The experiment of decoy state QKD has been demonstrated using ID-3000 commercial QKD system based on a standard bi-directional ‘Plug & Play’ set-up. Two protocols of decoy state QKD have been implemented: one decoy state protocol and vacuum state protocol for both BB84 and SARG04 over different transmission distance of standard telecom fiber. We have achieved a low quantum bit error rate of signal state from 10 to 50 km. The results have shown that the gains of signal are greater than decoy state gains and the QBERs of signal are less than decoy state QBERs. The experimental results are in excellent agreement with simulation results.
