Quantum computing has been rapidly evolving as a field, with innovations driven by industry, academia, and government institutions. The technology has the potential to accelerate computation for solving complex problems across multiple industrial sectors. Finance and economics, with many problems exhibiting computationally heavy requirements, comprise a high-profile sector where quantum computing could have a significant impact. Therefore, it is important to identify and understand to what extent the technology could find utility in the sector. This technical review is written for quantum applications researchers, quantitative analysts in finance and economics, and researchers in related mathematical sciences. It is divided into two parts: (i) a survey of quantum algorithms pertinent to problems in finance and economics, and (ii) mapping of several use cases in the sector to the potential quantum algorithms presented in part (i). We discuss some challenges on the pathway to achieving quantum advantage. Ultimately, this review aims to be a catalyst for interdisciplinary research that will accelerate the advent of the practical advantages of quantum technologies to solve complex problems in this sector.

Quantum technology is evolving rapidly with a potential to influence financial services. While quantum computing offers strong prospects for improving predictive analytics, risk management, and portfolio optimisation, its integration into financial systems remains constrained by algorithmic redesign requirements and technological limitations. This study reviews and synthesises research at the intersection of quantum computing and finance to map prevailing trends, thematic concentrations, and future inquiry paths. A systematic search of Web of Science and Scopus (2000–2023) identified 75 relevant studies, which were analysed using VOSViewer and Biblioshiny. The analysis shows that scholarly interest in quantum applications to finance accelerates only after 2020, indicating a temporal lag relative to the broader quantum computing literature. Four thematic clusters emerge: quantum cryptography and security, financial data processing, quantum algorithms for finance, and quantum machine learning. These areas reflect differing levels of maturity but reveal a shared emphasis on high-complexity modelling, enhanced data processing, and secure transaction frameworks. The review underscores the need for deeper algorithmic refinement, robust validation of financial use cases, and interdisciplinary collaboration among physicists, computer scientists, and finance researchers. Advancing these fronts will be essential for translating quantum potential into practical, scalable financial innovations.
Quantum computers are expected to surpass the computational capabilities of classical computers during this decade and have transformative 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 survey paper presents a comprehensive summary of the state of the art of quantum computing for financial applications, with particular emphasis on stochastic modeling, optimization, and machine learning, describing how these solutions, adapted to work on a quantum computer, can potentially help to solve financial problems, such as derivative pricing, risk modeling, portfolio optimization, natural language processing, and fraud detection, more efficiently and accurately. We also discuss the feasibility of these algorithms on near-term quantum computers with various hardware implementations and demonstrate how they relate to a wide range of use cases in finance. We hope this article will not only serve as a reference for academic researchers and industry practitioners but also inspire new ideas for future research.
Quantum computing, leveraging the principles of quantum mechanics, is emerging as one of the most transformative technologies of the 21st century, promising computational power that can tackle problems once considered unsolvable. Unlike classical computing, which processes data in bits, quantum computing operates using quantum bits or ‘qubits’ that exploit quantum superposition and entanglement, enabling vastly superior processing power. This paper examines the challenges and opportunities presented by quantum computing, focusing on its potential to transform various industries such as healthcare, finance, education, defence, utilities and more. Additionally, the paper explores its environmental implications and impact on sustainability. A literature survey of key research contributions and a discussion of commercial timelines highlight the current state and future of this revolutionary technology. While quantum computing presents immense opportunities, its technical and economic challenges must be overcome for it to reach widespread commercial adoption. The paper concludes with an exploration of the road ahead for this nascent technology. Despite significant challenges, quantum computing offers unprecedented opportunities to transform multiple sectors, making it an essential area for ongoing research.
Quantum computers can solve specific problems that are not feasible on "classical" hardware. Harvesting the speed-up provided by quantum computers therefore has the potential to change any industry which uses computation, including finance. First quantum applications for the financial industry involving optimization, simulation, and machine learning problems have already been proposed and applied to use cases such as portfolio management, risk management, and pricing derivatives. This survey reviews platforms, algorithms, methodologies, and use cases of quantum computing for various applications in finance in a structured way. It is aimed at people working in the financial industry and serves to gain an overview of the current development and capabilities and understand the potential of quantum computing in the financial industry.
The aim of this research is to investigate the effects of quantum computing on financial analysis and forecast accuracy. Given the significant increase in the volume of financial data and the complexity of financial decision-making, the need to use new technologies such as quantum computing is increasingly felt. The research collected data from 100 financial analysts, researchers, and IT professionals, as well as conducted in-depth interviews with twenty experts. The findings show that 70% of respondents emphasize that quantum computing can effectively increase the accuracy of financial forecasts. However, significant challenges have been identified, such as high costs and the need for complex infrastructure to implement the technology. Additionally, 35% of professionals express concerns about data security and privacy. Finally, this paper offers recommendations that include investing in human resource development and establishing new security protocols to best exploit the potential opportunities of quantum computing. This research can help better understand the impact of quantum computing innovations on the future of the financial industry and provide practical solutions to address emerging challenges. Also, more detailed studies on the social and economic impacts of this technology on financial markets and how it interacts with other technologies could enrich the results of this research.
Quantum computation holds the promise of highly efficient algorithms, provides exponential speedups for specific technologically significant problems, plays the most promising role in quantum technological progress, and has transformative potential in numerous industry sectors. In quantum computing, finance is recognized as one of the most beneficial areas because of the potential for many financial cases that can be solved by quantum algorithms suitable for noisy-intermedia-scale quantum(NISQ) computers. The benefits of quantum computing are colossal time and computational memory reduction with which the computational tasks are performed, which leads to the accuracy of the computations. This paper presents a comprehensive summary of quantum computing for traditional and Blockchain financial applications.
