Secure Key Fraction (SKF = ℓ/N) vs. radial postselection parameter for different testing ratios rT. The green curves represent the theoretical SKF for assumed (constant) 92% error-correction efficiency, the orange dots illustrate the secure key fraction for the experimental data. The numbers in the balloons state the average efficiency \(\bar{\beta }\) of LDPC codes used for error-correction, while the color of the balloons indicates the code rate R
