Experimental Characterization and Model Validation of Interference in Classical-QKD Coexistence Transmission

Published 16 Feb 2026 in quant-ph | (2602.15910v1)

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.
