Efficiency of coherent-state quantum cryptography in the presence of loss: Influence of realistic error correction

We investigate the performance of a continuous-variable quantum key distribution scheme in a practical setting. More specifically, we take a nonideal error reconciliation procedure into account. The quantum channel connecting the two honest parties is assumed to be lossy but noiseless. Secret key ra...
