Countdown to Q-Day: The Global Race to Rewrite Encryption
Inside the Urgent Migration Before Quantum Computers Break the Internet

About this book:

Imagine a morning when the padlock icon in your browser vanishes—not from a glitch, but because the math protecting your bank account, medical records, and the power grid has been solved in seconds by a quantum computer. That moment is Q-Day, and it’s closer than you think. *Countdown to Q-Day* pulls back the curtain on the most high-stakes technological race in history: the desperate, global scramble to rewrite the encryption foundations of the entire internet before "Store Now, Decrypt Later" adversaries unlock decades of harvested secrets. From the dilution refrigerators of IBM and Google to the classified war rooms where nations project the timeline, this book reveals why the cryptographic armor of the modern world has an expiration date—and why we are already living in the vulnerability window.

You’ll go inside the NIST standardization battle where mathematicians stress-test exotic new lattices to replace RSA, witness the geopolitical chess match over who controls the next century’s standards, and confront the "legacy trap" of millions of unpatchable devices—from satellites to pacemakers—hardcoded with breakable keys. It’s a story of human bottlenecks, supply-chain sabotage risks, and the terrifying economics of a migration that must happen on a running plane. Whether you’re a policymaker, engineer, or simply a citizen of the digital age, this is the definitive account of the invisible war to secure the future before the quantum sword falls.
