Beyond Q-Day

This book provides a strategic blueprint for navigating the quantum-AI convergence before Q-Day-the day quantum computers break current cryptography. It argues that the convergence of quantum computing and artificial intelligence creates a governance crisis demanding institutional transformation, strategic foresight, and international cooperation. The book offers actionable frameworks for policymakers and organizational leaders: crypto-agile architecture, AI governance systems, strategic foresight methodologies, and institutional adaptation roadmaps. It examines vulnerabilities in critical infrastructure, financial systems, and digital identity, while addressing asymmetric exposure of emerging economies. The central message is that those who act now will shape the post-quantum world; those who delay will be shaped by it. The window for proactive action is closing. The time to act is now.
