- *Estimated including 3.35% (average of measured QBERs during calibration measurements) net QBER contribution (i.e. 93.3% entanglement fidelity contribution) from entangled photon pair source, user modules, timing jitter, detectors and polarization compensation.
- † The actual experimentally measured value depends on the properties of the network link and thus there is a nearly uniform spread of QBER values between the extremes quoted
