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 IBM, Google, and SandboxAQ, and explain the Y2K-like urgency of a transition that lacks a fixed deadline. Lucas and Luna stress that this isn’t a distant threat — it’s a supply-chain and compliance issue already appearing on CISOs’ radars. The episode closes with a practical takeaway: inventory your cryptographic assets today, because migrating 10,000 certificates takes years.
