Which failure results when polarization entangled photons undergo decoherence?

💡 Explanation

Reduced quantum key distribution security failure happens because decoherence collapses the entangled state, destroying the correlations needed for secure key exchange via quantum cryptography, therefore security is directly impacted rather than benefiting from increased efficiencies or entanglement fidelity under optimal secure handling.
