Published in 2018 at "npj Quantum Information"

DOI: 10.1038/s41534-018-0070-6

Abstract: The speed at which two remote parties can exchange secret keys in continuous-variable quantum key distribution (CV-QKD) is currently limited by the computational complexity of key reconciliation. Multi-dimensional reconciliation using multi-edge low-density parity-check (LDPC) codes… read more here.
