Table 2 A summary of the impacts of sampling device under the QRNG with imperfect FRM
From: Effect of external magnetic fields on practical quantum random number generator
Sampling range | Sampling resolution | Normalized conditional min-entropy | Security of the QRNG | Solution |
|---|---|---|---|---|
Below threshold value | Normal | Not overestimated | Not affected | None |
Exceed threshold value | Normal | Not overestimated | Affected | Setting a suitable sampling rangeand increasing the sampling resolution, as well as the other solutions in Sect. 3.2. |
Exceed threshold value | Larger | Smaller the amount of overestimation | Less affected |
