Quantum computing and financial markets: what you need to know
Quantum computing is a rapidly evolving field of technology that promises to revolutionize the way we process and analyze data. The Bank of Finland is actively engaged in international collaboration on this cutting-edge technology, and is also participating in national initiatives, such as the VTT consortium on quantum technology.
Quantum computers use quantum bits (qubits) instead of classical bits. This allows them to exploit quantum phenomena such as superposition and entanglement to perform multiple calculations simultaneously, potentially achieving exponential speedups over conventional computers.
Finance has been signaled as one of the biggest beneficiaries of this new technology
Quantum computing has many potential applications in various domains, and finance has been signaled as one of the biggest beneficiaries of this new technology. Finance is a highly digitalized industry that features many complex and data-intensive tasks, such as derivatives pricing, risk modeling, and portfolio optimization. Quantum algorithms could offer significant advantages in these areas, enabling faster and more accurate solutions than current methods based on classical computing.
However, quantum technology also poses some challenges and risks for the financial system. One of the most pressing issues is that quantum computers could be able to break the current encryption systems based on public keys using the Shor’s algorithm. These encryption methods protect the security and integrity of financial data and transactions. Hence the Department of Homeland Security (DHS), in partnership with the Department of Commerce’s National Institute of Standards and Technology (NIST) have called for the development and adoption of quantum-resistant encryption standards and protocols, as well as the International Monetary Fund (IMF) recommends enhancement of the cryptographic agility of existing systems.
Quantum technology still faces many technical and practical obstacles before it can reach its full potential
While quantum technology is still in its early stages and faces many technical and practical obstacles before it can reach its full potential, the recent progress and investments in this field indicate that quantum computing could become a reality in the near future. Therefore, it is important for financial institutions and regulators to be aware of the opportunities and challenges of quantum technology, and to prepare for the quantum era.
