Blind Information Reconciliation With Polar Codes for Quantum Key Distribution

We suggest a new protocol for the information reconciliation stage of quantum key distribution based on polar codes. The suggested approach is based on the blind technique, which is proved to be useful for low-density parity-check (LDPC) codes. We show that the suggested protocol outperforms the blind reconciliation with LDPC codes, especially when there are high fluctuations in quantum bit error rate (QBER).

Automated summary

A new protocol based on polar codes using blind technique for information reconciliation stage in quantum key distribution outperforms blind reconciliation with LDPC codes, especially in cases of high QBER fluctuations.
