Quantum Key Distribution
Quantum laws guarantee security by making eavesdropping physically detectable

Why does quantum key distribution provide security that classical cryptography cannot guarantee?
Because it uses longer keys than classical cryptography, making brute force impossible.
Because quantum keys can be perfectly cloned to ensure backup security.
Because any attempt to measure or copy the quantum key disturbs it, revealing eavesdropping.
