SargSifting
Tier A: SARG04's conclusive-exclusion sifting, a quarter where BB84 keeps a half
4/4 passed in 0ms
| Test | What it does | Result |
|---|---|---|
test_gain_is_poisson_sum | sarg_gain's gain and QBER equal the Poisson sums of the per-photon-number yields to 1e-15. | ✅ pass |
test_ideal_quarter | sarg_sift is 1/4 at aligned detectors, against BB84's 1/2, and RISES with misalignment to 0.2665 at the GYS e_det. | ✅ pass |
test_vacuum_yield | Y_0 is half the background and e_0 is 1/2, and a vanishing yield returns e = 1/2 rather than dividing by zero. | ✅ pass |
test_yield_is_half_bb84 | The n-photon yield is half BB84's at aligned detectors with no dark counts, and the GYS bit error rate 1.876 times BB84's at n = 1 and 2. | ✅ pass |
