Fig. 3: Comparison with other protocols.
From: Tight finite-key analysis for quantum key distribution without monitoring signal disturbance
The full lines show the secret key rate versus total emitted pulses. The red curve represents the finite-key analysis of decoy-state BB84 protocol in ref. 18. The yellow curve represents the original finite-key analysis of RRDPS protocol given in ref. 5. The green curve represents the key rate based on our corollary. We set L = 53. The total security parameter of the final key is ϵtot: = 10−10. The channel loss is fixed at 20dB, dark counts rate is d = 10−6 per pulse, and the misalignment of measurement is emis = 0.015. The efficiency of error correction ξ is 1.1.
