  In this paper, we present an information reconciliation protocol designed for
Continuous-Variable QKD using the Distributional Transform. By combining tools
from copula and information theory, we present a method for extracting
independent symmetric Bernoulli bits for Gaussian-modulated CVQKD protocols,
which we called the Distributional Transform Expansion (DTE). We derived the
expressions for the maximum reconciliation efficiency for both homodyne and
heterodyne measurements, which, for the last, is achievable with an efficiency
greater than 0.9 at a signal-to-noise ratio lower than -3.6 dB.
