Quantum quantitative finance

The field of quantum computing has been developing rapidly since the beginning of the 21st century, with many large companies investing in research and development in this area. Finance is considered one of the top four industries likely to see the earliest economic impact from quantum computing. Nevertheless, the initial excitement among banks is fading as the leap needed for real-life applications is still significant. This paper analyzes potential applications of quantum computing to finance and provides cases where quantum computing is already used in production. Detailed implementations of portfolio optimization using quantum technologies are examined, offering essential tools for finance professionals without a background in physics. It is important to prepare for advancements in quantum computing ahead of their full realization to gain a competitive advantage, mitigate future risks, and foster innovation.
