Simulating the Unsimulable: Materials, Chemistry, Finance

Some systems are too complex to model accurately—until quantum mechanics becomes the computer itself. Simulating the Unsimulable: Materials, Chemistry, Finance focuses on the original promise of quantum computing: understanding systems nature refuses to simplify.
This book takes a domain-first approach. It shows how quantum simulation addresses real problems in molecular behavior, material properties, and financial dynamics where approximation breaks down. Instead of abstract benchmarks, it examines why classical simulations fail as interactions scale—and how quantum models mirror the physics they simulate.
Readers gain insight into how quantum computers represent molecules, energy states, and correlated systems more naturally than classical machines ever could. The book emphasizes *why simulation is where quantum advantage appears earliest*, long before general-purpose quantum computing arrives.
Readers will examine:
• Why chemistry and materials strain classical simulation
• How quantum systems model other quantum systems
• Where approximation becomes unacceptable
• How finance benefits from complex system modeling
• What makes simulation the most realistic early use case
This book is for scientists, engineers, and analysts who work at the edge of computability. If your problems resist simplification, this book explains why quantum simulation changes what is possible—and where it matters first.
