Practical decoy state for quantum key distribution

Decoy states have recently been proposed as a useful method for substantially improving the performance of quantum key distribution QKD . Here, we present a general theory of the decoy state protocol based on only two decoy states and one signal state. We perform optimization on the choice of intensities of the two decoy states and the signal state. Our result shows that a decoy state protocol ...

Expeditious Reconciliation for Practical Quantum Key Distribution

The paper proposes algorithmic and environmental modifications to the extant reconciliation algorithms within the BB84 protocol so as to speed up reconciliation and privacy amplification. These algorithms have been known to be a performance bottleneck 1 and can process data at rates that are six times slower than the quantum channel they serve. As improvements in single-photon sources and detec...

Finite-key analysis for practical implementations of quantum key distribution

The lists of bits processed in quantum key distribution are necessarily of finite length. The need for finite-key unconditional security bounds was recognized long ago, but the theoretical tools have become available only very recently. We provide finite-key unconditional security bounds for two practical implementations of the Bennett–Brassard 1984 coding: prepareand-measure implementations wi...
