Tier B: Ling et al. 2008, an E91 key rate priced by a measured violation
7/7 passed in 0ms
| Test | What it does | Result |
|---|---|---|
test_ling_accidentals | The 0.5% accidental coincidences contribute 0.250 points of error, 4.3% of the 5.806% the violation implies. | ✅ pass |
test_ling_anisotropy | Declared caveat: below the depolarising 5.806% the ceiling only rises above 300 bit/s, their "residual distinguishability" putting the true QBER lower. | ✅ pass |
test_ling_assumption | On their numbers BBM92 pays 813.33 bit/s against the CHSH price's 308.41, 2.637 times. | ✅ pass |
test_ling_ceiling | S = 2.5 on a depolarised singlet fixes the bit error at 5.806%, and the Shannon-limit rate is 308.41 bit/s against the measured 292.40-300. | ✅ pass |
test_ling_measured | The depolarising bridge inverts to S = 2.5 exactly, and ekert_rate refuses source="modelled" for this fielded violation. | ✅ pass |
test_ling_qber | Inverting the 300 bit/s throughput gives a 5.899% bit error against the 5.806% the violation implies, 0.093 points apart. | ✅ pass |
test_ling_throughput | 10^7 bit over 9.5 hours is 292.40 bit/s against their "around 300 bit/s". | ✅ pass |
