Quantitative assessment of interference effects from SpRS and FWM
Enhanced understanding of noise sources in QKD coexistence
Abstract
We present an experimental characterization of coexistence-induced interference in QKD transmission arising from SpRS and FWM, validating a comprehensive semi-analytical model for accurate noise estimation. Experimental results show good agreement with theoretical predictions.
