The Quantum Economy explains why quantum computing is becoming economically relevant now, not someday in the distant future. Quentin G. Dalton shows how quantum and AI are converging into a strategic force that could reshape finance, industry, cybersecurity, and global competition. Written for business leaders, investors, policymakers, technologists, and informed readers, this book offers a clear framework for understanding the coming quantum economy and the choices it will force on companies and nations. Rather than treating quantum as a narrow technical milestone, Dalton places it in the larger context of computing limits, AI's growing demand for resources, and the race for advantage among firms and governments. The result is a timely, accessible guide to the economic stakes of a new computing era. Readers will come away with a sharper understanding of why quantum progress matters before full-scale maturity, how hybrid computing architectures may emerge, and what strategic questions decision-makers must confront as the frontier of power shifts.
