White Paper: Quantum in Finance
Authors: Dr. Tobias Denzler & Fraser Levick, QAI Ventures
How will quantum technologies transform the financial industry? Which early applications are most likely to deliver real value? And what actions should financial institutions take today to prepare?
At QAI Ventures, we believe in a multi-stakeholder approach to bringing quantum technologies to market. By connecting capital, founders, and industry stakeholders early, we accelerate the journey from scientific breakthrough to commercial impact. A key part of this strategy is focusing on sectors where the signals of adoption are strongest, and finance is emerging as one of the first industries where quantum technologies are beginning to create an impact.
To assess the current state of the market and identify the most promising real-world applications, the QAI Ventures team conducted an extensive review of academic research and engaged directly with executives, founders, academics, and policymakers across the quantum and financial ecosystems. The result is this white paper.
Its central conclusion is clear: quantum technologies have become a strategic imperative for financial institutions. Quantum advantage is unlikely to arrive overnight, but organizations that delay preparation risk being caught off guard when it does. Talent shortages, lengthy integration cycles, and evolving regulatory requirements mean the window for proactive positioning is narrowing.
Two areas, in particular, demand immediate attention.
Quantum security presents an urgent challenge. The threat to existing cryptographic infrastructure is already real. The "harvest now, decrypt later" attack vector means sensitive data can be collected today and compromised in the future once sufficiently powerful quantum computers become available. As a result, the transition to post-quantum cryptography (PQC) is no longer a future concern but a present-day priority. Early adopters have found that migrating to PQC is a complex, organization-wide effort that requires years rather than months.
Quantum computing offers compelling opportunities in midterm, particularly in stochastic simulation and machine learning. These are areas where quantum algorithms and where hybrid quantum-classical approaches are already showing encouraging results. Other applications, such as portfolio optimization and broader computational finance use cases, are likely to emerge over a longer horizon as hardware advances toward fault tolerance, a milestone leading providers are currently targeting around 2030.
This white paper explores the opportunities, challenges, and strategic considerations that will define the future of quantum in finance, providing executives and technical personnel in the finance industry with a practical framework for navigating the transition ahead.
