Q-Day Horizon: The Urgent Race for Quantum-Safe Cryptography

As quantum hardware scales toward cryptographically relevant milestones, Q-Day threatens to shatter RSA and ECC encryption, exposing trillions in encrypted data to 'harvest now, decrypt later' risks. NIST's PQC standards offer a bulwark, yet adoption stalls amid policy shifts and scalability hurdles. This convergence of quantum, AI, and cybersecurity demands systemic recalibration to safeguard digital economies.
