Efficient Information Reconciliation for High-Dimensional Quantum Key Distribution (2307.02225v2)
Published 5 Jul 2023 in quant-ph
Abstract: The Information Reconciliation phase in quantum key distribution has significant impact on the range and throughput of any QKD system. We explore this stage for high-dimensional QKD implementations and introduce two novel methods for reconciliation. The methods are based on nonbinary LDPC codes and the Cascade algorithm, and achieve efficiencies close the the Slepian-Wolf bound on q-ary symmetric channels.
