Figure 2: Comparison of key rate with earlier results.

From: Tight finite-key analysis for quantum cryptography

Figure 2

The plots show the rate ℓ/N as a function of the sifted key length N=n+k for various channel bit error rates Q (as in Fig. 1) and a security bound of ɛ=10−10. The (curved) dashed lines show the rates that can be proven secure using ref. 18. The horizontal dashed lines indicate the asymptotic rates for Q∈{1%, 2.5%, 5%} (from top to bottom).
