Performance Evaluation of Scalar Reconciliation for Continuous-Variable Quantum Key Distribution

The existing robust technique, Scalar Reconciliation combined with a Continuous-Variable Quantum Key Distribution is investigated in this paper with the help of simulations in terms of the symbol error rate. The solution contains efficient logical layer-based reconciliation for Continuous-Variable Quantum Key Distribution techniques, which extract the binary information from correlated Gaussian variables. The algorithm has been extended by different assumptions related to the raw data generation method and the segmentation of the key symbols to be transmitted. The performance of the extended algorithm has been investigated in terms of the symbol error ratio.
