Quantum Capabilities: From Strategic Concept to Market Reality

Quantum Computing is edging closer to the boardroom as attention turns to Q-day: the point at which a cryptographically relevant quantum computer could challenge the encryption standards beneath modern markets, payments, custody, identity and data security. That makes Quantum uncomfortable but also full of opportunity. The risks are real, but so are the exciting opportunities it brings for portfolio optimisation, risk modelling and cyber defences. 

For our Quantum Special, we have put together a four-part series that moves from first principles through to what quantum could mean for financial markets, investment, institutional deployment and the emerging regulatory landscape. We round things off with 10 key takeaways and an ecosystem spotlight for anyone wondering where to look next.

Our Practice Lead and resident astrophysics survivor, Andrew Dunn, decodes the complex mechanics of quantum computing to answer a crucial question: ‘Why should FinTech care?’  Read the first article in our four-blog series to understand why this cryptographic arms race threatens the stability of the global economy. Settle in, this is a long-form read.

With 80% of the largest global banks already exploring its applications, quantum computing is a present commercial reality. Read part two of our series to discover how financial institutions are simultaneously building post-quantum cryptographic defences and deploying offensive quantum algorithms to optimise portfolios and detect fraud.  

Our third piece explores the regulatory urgency driving the financial sector’s cryptographic overhaul. With global quantum investment reaching $12.6 billion in 2025, discover how institutions must navigate strict 2035 migration deadlines and cross-border compliance mandates to secure critical infrastructure. 

What must financial leaders understand about the impending quantum shift? This final instalment outlines the ten essential facts for the sector, from immediate data decryption threats to complex migration strategies and using quantum to transform risk modelling, portfolio optimisation, cybersecurity, and fraud detection.

Ecosystem Spotlight: Further Quantum Reading

Quantum technology is nearing a commercial tipping point. McKinsey’s 2026 Quantum Technology Monitor reveals surging investment, growing revenues, and real-world industry adoption as organisations move from experimentation to value creation. With trillions in economic potential at stake, the race to secure quantum advantage is accelerating.

Central bank digital currencies are moving from concept to reality. A BIS survey finds that emerging economies are leading development efforts, with central banks representing one-fifth of the world’s population likely to issue CBDCs in the near future. The findings signal a major shift in the future of money and payments.

Quantum computing promises major gains for financial services, but it also threatens the cryptographic foundations of the global financial system. A joint World Economic Forum and FCA report outlines four principles for a quantum-secure transition, urging regulators and industry leaders to collaborate now to strengthen resilience, harmonise standards, and manage emerging risks.

Quantum computing could reshape financial services through advances in portfolio optimisation, machine learning, and risk modelling. A new FCA research note finds that commercial applications are drawing closer, prompting firms and regulators to build quantum readiness strategies now. The message: prepare early to capture opportunities and manage emerging risks.
