Which fundamental risk arises when distributing entangled photons via optical fiber?

💡 Explanation

Decoherence occurs because interaction with the fiber environment disturbs the entangled state, causing loss of quantum correlation rather than simple photon loss. Therefore, entanglement degrades information and correlations rather than just signal strength.
