← ScienceWhich measurement outcome statistically guarantees quantum communication using entangled photons?
A)Bell state violation observed✓
B)Consistent frequency spectrum matching
C)Polarization angle exceeding 45 degrees
D)Symmetrical spatial distribution occurs
💡 Explanation
Observed Bell state violation guarantees entanglement because it demonstrates correlations stronger than any classical explanation allows, therefore a secret key may be shared rather than merely correlated measurement, where classical correlations suffice.
