Quantum computers are expected to surpass the computational capabilities of classical computers during this decade, and achieve disruptive impact on numerous industry sectors, particularly finance. In fact, finance is estimated to be the first industry sector to benefit from quantum computing not only in the medium and long terms, but even in the short term. This review paper presents the state of the art of quantum algorithms for financial applications, with particular focus to those use cases that can be solved via machine learning.
The paper takes a look at several financial applications that take advantage of techniques based on various quantum regression algorithms. The financial applications include asset pricing, multi-asset trend following strategies, and implied volatility estimation.
