    "abstract": "In this paper, we propose how to simply construct a pair of linear codes for\nthe BB84 quantum key distribution protocol. This protocol allows unconditional\nsecurity in the presence of an eavesdropper, and the pair of linear codes is\nused for error correction and privacy amplification. Since their high decoding\nperformance implies low eavesdropper\u0027s mutual information, good design of the\ntwo codes is required. The proposed method admits using arbitrary low-density\nparity-check (LDPC) codes. Therefore, it has low complexity and high\nperformance for hardware implementation. Simulation results show that the pair\nof codes performs well against practical and various noise levels.",
