Reverse Reconciliation with Soft Information for Discrete-Modulation CV-QKD at Long Range
📝 Abstract
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.
