This addresses the challenge of secure quantum key distribution for long-range communication, but appears incremental as it builds on a previously introduced scheme.
The paper tackles the reverse reconciliation problem in discrete-modulation CV-QKD at long range by assessing a recently introduced scheme with soft information at ultra-low SNR, proving it is a versatile solution.
We recently introduced a reverse reconciliation scheme with soft information. In this paper, we assess its performance at ultra-low SNR, thus proving that such scheme is a versatile solution to the reverse reconciliation problem.
