: Uses error-correcting codes to create security.

: This is a "leap" in agility; organizations must move toward crypto-agility , allowing them to swap out compromised algorithms without rebuilding entire systems. 2. Quantum Key Distribution (QKD)

: Based on the Observer Effect , any attempt to eavesdrop on a quantum signal changes its state, immediately alerting the senders.

Security is rarely just a technical problem. A "quantum leap" is also required in how we manage data lifecycle:
