Which risk increases when attempting quantum key distribution via fiber given inherent fiber polarization mode dispersion?

💡 Explanation

Increased polarization fluctuations during entanglement result in increased quantum bit error rate when reconciliation keys across distant secure endpoints; because the polarization changes alter photonic transmission correlation—rather than solely reducing efficiency—therefore the QBER rises rather than solely decreasing entanglement metrics.
