TestWhat it doesResult
test_sarg_ladderDeclared miss: their figure 2 ladder needs efficiency 0.17770 against 0.16636 from eta_Bob = 0.40 and 3 dB/km, 6.8% over, reversing to 1.1% under at eta_opt eta_det = 0.432.✅ pass
test_sarg_qber_lawWeak-signal and background-free, the engine gives the paper's (1 - V)/2 = 2.300% for BB84 and (1 - V)/(2 - V) = 4.398% for SARG04 at V = 0.954.✅ pass
test_sarg_qber_missDeclared miss: at mu = 0.19 the engine gives 2.502% and 4.753% against their ~3% and ~5%, a shortfall dark counts do not carry.✅ pass
test_sarg_ratioAt V = 0.954 the SARG04-to-BB84 sifted ratio (e_det/2 + 1/4) over 1/2 is 0.5230, against 0.52075 averaged over their six figure 2 pairs, each above 1/2.✅ pass
test_sarg_siftingsarg_sift at a perfect frame is exactly 1/4, their measured 0.25 +/- 0.01, half BB84's 0.50.✅ pass
test_sarg_three_waysV = 0.954, the sifted-rate ladder's 0.95850, the BB84 QBER's 0.94000 and the SARG04 QBER's 0.94737 each fix the visibility, a 1.97% spread.✅ pass
