Quantum Entanglement Explained: How It Powers Quantum Key Distribution—and Why the NSA Still Urges Caution
Quantum Key Distribution (QKD) leverages quantum entanglement to create secure communication keys, promising eavesdropping detection. However, the NSA and research highlight that its security is highly implementation-dependent, not solely assured by physics, due to practical limitations and vulnerabilities.
