Rate-Compatible Polar- and LDPC-Coded Hybrid ARQ Aided Reverse Reconciliation in CV-QKD

IEEE Open Journal of Vehicular Technology
Continuous-variable quantum key distribution (CV-QKD) systems face challenges in maintaining efficient reconciliation over long distances due to the time variant signal-to-noise ratio (SNR) imposed by channel quality fluctuations.
