Which challenge arises when exploiting quantum entanglement for secure communication?

💡 Explanation

Entanglement-based quantum key distribution depends on transmitting entangled photons; therefore, decoherence increases because photons interact with silica over long distances disrupting quantum states. Maintaining entanglement poses challenges rather than other properties such as superposition or key generation automatically.
