| High effective efficiency LDPC codes for CV-QKD | QCRYPT 2021 | Thomas Symul, Andrew Lance |
High efficiency error reconciliation, typically achieved by using Multi Edge Low Density Parity Codes (ME-LDPC), is necessary for CV-QKD to reach large transmission distance. The commonly accepted definition of the efficiency, however, is problematic as it does not take into account the Frame Error Rate (FER) of LDPC, and therefore is theoretically and provably unbounded (i.e. can tend to infinity), if one can accept increasingly larger FER. Here we report new ME-LDPC code construction allowing high efficiency (>0.91) with very low FER (<0.008), allowing for a large effective efficiency, over a large continuous range of SNR (between -20.5dB to -6dB). |
