← ScienceWhich risk increases during quantum key distribution due to corrupted entanglement?
A)Shared key divergence✓
B)Photon polarization drift
C)Detector saturation damage
D)Qubit lifetime decline
💡 Explanation
Shared key divergence increases because errors introduce discrepancies arising from imperfect preparation, measurement of entangled photons, and environmental noise; therefore security compromises the shared key distribution, rather than simply polarizing or signal decay, due to eavesdropping attempts, that would be indicated by errors.
