Which consequence results when a quantum key distribution (QKD) network link is probed using intercept-resend attack?

💡 Explanation

Entanglement fidelity degrades because the intercept-resend attacks attempts to measure the qubits, collapsing their entangled states through quantum decoherence; therefore, secure key exchange fails between sender and receiver rather than enabling faster key generation by other means.
