← ScienceWhich error prevalence increases when calibrating entangled photon sources?
A)High idler detection dead time
B)Incorrect pump laser polarization
C)Spurious correlations misidentification✓
D)Wavemeter wavelength calibration offset
💡 Explanation
Spurious correlations are misidentified because the entanglement verification relies on the Bell test; therefore, accidental coincidences mimicking true entanglement increase measurement errors significantly, rather than other calibration parameter errors.
