The current security infrastructure relies on mathematical problems (like RSA and ECC) that are easy for classical computers to solve but would be trivial for a sufficiently powerful quantum computer using . This creates a "Harvest Now, Decrypt Later" threat, where adversaries steal encrypted data today to unlock it once quantum technology matures. 1. Post-Quantum Cryptography (PQC)
: 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:
