Tx-Rx Mode Mismatch Effects in Gaussian-Modulated CV QKD
arXiv:2504.20632
Abstract
The impact of technical limitations on pulse shaping used to generate a CV QKD signal is quantified in terms of the attainable secure key rate. Optimization of key spectral efficiency for Gaussian-modulated CV QKD with truncated and discretized root-raised cosine profiles is discussed.
