Quantum: The next frontier for financial services

The financial services sector is investing in exploratory quantum applications, developing and testing compelling use cases with the aim of gaining a competitive advantage.

Quantum: A new paradigm of computing

The financial services sector has historically been at the forefront of adopting technology to deliver stakeholder value. A high data and computation-intensive sector, it requires many applications to perform highly complex mathematical calculations. 

With continuously changing environments due to various economic and geopolitical factors, the sector is exposed to increased complexity, risks, agile competition and uncertainty, leading to significant volatility.  

The industry needs to solve these problems in real time to maximize returns, but many quickly become intractable on currently available classical computational platforms. However the advent of quantum computers offers a new paradigm of computing, promising to solve some of the most complex, computationally challenging problems across banking, financial markets and insurance domains.

Exploration into key applications and early implementation

Quantum stochastic modelling approaches could help financial organizations to comply with regulatory requirements ranging from meeting parameters like value at risk, liquidity and capital allocation values, and help in the pricing of financial assets, such as derivatives.

Quantum computers are very effective in large optimization problems, so FS applications like optimization of asset portfolios.  Also, quantum machine learning techniques are evolving fast and promise a wider tool kit for solving many financial applications, ranging from anomaly detection for fraud detection and money laundering, time series-based asset pricing and implied volatility estimation of assets, to credit score classification and more. Although full-scale fault-tolerant quantum computers are still some years away, some leading financial institutions and Capgemini’s Quantum Lab are exploring proofs of concept to see how quantum could be applied and generate operational benefits.

Quantum safe cryptography – a key requirement 

Financial institutions handle large amounts of personal information and financial transactions, with a responsibility to maintain the privacy, security and integrity of these transactions. With unprecedented computing capabilities, quantum computers could break some of the current public key encryption mechanisms used in many financial applications for security and privacy. 

Even though this scenario is far off, this risk is already here due to the harvest-now-decrypt-later threat. So financial institutions need to start thinking now about how this might impact their resilience today and in the future.

A first step is to implement a crypto agility approach – well-defined processes and systems equipped to rapidly adapt, mitigate, and handle any security challenges.  Capgemini helps its clients achieve crypto agility and quantum safe cryptography across their IT landscape. 

Capgemini is a leading partner for its clients on their quantum journey. By combining our sector expertise with that of our dedicated Quantum Lab, we help identify use cases with real future business value, develop and deploy an early quantum roadmap, explore proofs of concept and their scalability in a business context. This is designed to accelerate the realization of a quantum advantage through measured/calibrated investments to achieve industry leadership.
