Reconciliation for Practical Quantum Key Distribution with BB84 protocol
This addresses the practical challenge of secure key exchange in QKD, but it appears incremental as it adapts existing channel coding techniques.
The paper tackles the problem of information reconciliation in quantum key distribution (QKD) with the BB84 protocol by proposing a new method based on Turbo codes, aiming to improve efficiency in the presence of an eavesdropper.
This paper investigates a new information reconciliation method for quantum key distribution in the case where two parties exchange key in the presence of a malevolent eavesdropper. We have observed that reconciliation is a special case of channel coding and for that existing techniques can be adapted for reconciliation. We describe an explicit reconciliation method based on Turbo codes. We believe that the proposed method can improve the efficiency of quantum key distribution protocols based on discrete quantum states.
