Cybersecurity faces a looming paradigm shift: quantum computers could break public-key encryption within a decade. In this episode, Lucas and Luna examine the ‘Q-Day’ timeline, starting with a concrete 2025 incident where a Chinese quantum team decrypted RSA-2048 in simulation. They explore why enterprises must start migrating to post-quantum cryptography now, despite high costs and uncertainty. The hosts discuss NIST’s finalized standards, the risk of ‘harvest now, decrypt later’ attacks, and why sectors like banking and healthcare are most exposed. They also highlight early movers such as…
