Quantum Economics and Finance: An Applied Mathematics Introduction

“If you are looking to learn more about quantum theory applied to finance, we highly recommend
reading David Orrell’s book: Quantum Economics and Finance: An Applied Mathematics
Introduction.” Quantum News

The word “quantum” is from the Latin for “how much” and in this book mathematician David Orrell
shows how it applies to the world of economic transactions. Written in clear and accessible
language, the book covers the essential mathematics behind topics such as quantum
cognition, option pricing, and quantum game theory, and delves into the nuts and bolts of
quantum mechanics, the principles of quantum economic modelling, and the basics of
quantum computation. On the way the reader will learn how quantum interference can be
used to model cognitive dissonance, how a quantum walk goes further than a random walk,
why market oscillations are real and imaginary at the same time, and how financial entanglement
explains the rate of mortgage default. It is aimed at anyone who wants to understand the
quantum ideas working their way into economics and finance, without getting drowned in
wave equations.

As interest in quantum computing grows, many companies from established banks to startups
are looking at ways to perform financial simulations using quantum algorithms. But what if we
should be using quantum models anyway – because the monetary system has quantum
properties of its own, and because they work?

The field is developing rapidly, and this third edition contains many updates including new
material on using quantum models to simulate the stock market.

David Orrell is an applied mathematician with extensive experience in mathematical modelling,
and the author of a dozen books on science and economics. The Economist calls him one of
the “leading proponents” of quantum finance, and notes that “One way or another,
finance will catch up.” This book will give the reader a head start.
