Abstract

We experimentally investigate quadrature imbalance compensation using Gram-Schmidt orthogonalization procedure (GSOP) for Gaussian-modulated CV-QKD. The results show that GSOP effectively corrects for quadrature imbalance allowing the same secret key fraction performance as a CV-QKD system with zero quadrature imbalance.
