Quantum Technologies Key Strategies and Opportunities for Financial Services Leaders 2025

Executive summary This white paper examines emerging applications of quantum technologies in financial services and highlights prominent case studies. Building on previous World Economic Forum reports focused on the quantum economy,1 quantum security2 and technology and innovation in financial services,3 this publication aims to support public- and private- sector leaders with insights that can help them navigate and prepare for quantum’s rapid evolution. While quantum technologies are still evolving, they are beginning to show potential as strategic differentiators. Financial services decision-makers that take thoughtful, measured steps today may be well-positioned to lead future innovation, strengthen security and build resilience in an increasingly complex digital landscape.As quantum technologies advance, emerging applications in financial services are offering valuable insights to public- and private-sector leaders. Key insights on quantum technologies for financial services FIGURE 1 Strategic imperatives for financial services For quantum to reach its full potential, engagement from policy-makers, industry leaders and academics is needed in six core pillars:Quantum computing Quantum computing offers the ability to solve highly complex optimization, simulation and data analysis challenges. Use cases include risk modelling, fraud detection and portfolio optimization, among many. Case studies from Yapı Kredi, Intesa Sanpaolo and Santander (among others) show early success in quantum and quantum-inspired applications.Quantum sensing Quantum sensing excels in highly precise measurements of physical quantities such as time, magnetic fields or acceleration. Use cases are limited, though include infrastructure monitoring and precise timing for high-frequency trading. This may have long-term potential in environmental, social and governance (ESG) reporting and sustainability- focused investing.Quantum security and quantum communications Quantum security can leverage post-quantum cryptography (PQC), quantum key distribution (QKD) and quantum random number generators (QRNG) to protect sensitive data. HSBC and Banco Sabadell (among others) are piloting quantum-secure infrastructure to mitigate future cyber threats. A defence-in-depth strategy – integrating quantum-resistant and quantum native technologies – is essential for long-term resilience.
