Which vulnerability arises from quantum entanglement in secure communication?

💡 Explanation

Entanglement creates correlated keys; therefore a compromise in one location breaks Post-Quantum Cryptography because eavesdropping uses quantum correlation, rather than relying on breaking encryption itself. Decoherence affects signal quality directly, not security.
