Blind information reconciliation with polar codes for quantum key distribution (2008.12299v1)
Published 27 Aug 2020 in quant-ph, cs.IT, and math.IT
Abstract: 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).
