Lloyds Banking Group has completed what is believed to be the first-known experiment exploring how quantum computing could help identify money mules, marking a significant milestone in the fight against economic crime.
According to FinTech Finance, the nine-month project, conducted in partnership with IBM, moves the technology from theoretical research into practical application, offering an early blueprint for how financial institutions could leverage next-generation computing to combat increasingly sophisticated criminal networks.
The experiment centred on money mule networks — a key enabler of scams and fraud in which criminal behaviour is concealed within vast webs of legitimate transactions. Using anonymised data on one of IBM’s 156-qubit quantum computers, the team tested multiple quantum algorithms to determine whether patterns of known money mule behaviour could be identified within a larger transactional graph. Critically, the solution successfully identified a real money mule that had been deliberately embedded in the data to validate the approach, demonstrating that quantum algorithms can untangle the exponentially complex transactional graphs that challenge traditional classical computers.
At the heart of the project is Lloyds’ growing internal quantum capability. The bank established a new working group of Quantum Ambassadors drawn from across the business, with qualifications in physics, mathematics and computer science. Over the course of the project, this team collaborated with Lloyds’ economic crime prevention experts and IBM’s specialists to explore how quantum computing could one day help uncover complex fraud patterns that prove challenging for traditional systems to detect. The significance of the experiment lies not just in identifying a single money mule, but in proving the technology’s potential to shift financial institutions from reactive monitoring to the proactive identification of sophisticated criminal networks.
Quantum computers differ fundamentally from traditional machines, which process information as bits representing either a 0 or a 1. Quantum computers use qubits, which follow the rules of quantum physics and can represent many states simultaneously. This means a quantum computer can assess all potential answers to a problem at the same time, rather than solving each sequentially — a capability that becomes particularly valuable when analysing large transaction networks where the number of possible patterns grows exponentially. For problems of this scale, a classical computer would theoretically require more machines than currently exist on the planet to achieve the same result.
The experiment is seen as a crucial early investment in building both the talent and infrastructure necessary to secure the future of financial services. Insights from this work could, in time, help banks detect sophisticated fraud earlier and better protect customers, as risk management demands continue to grow.
Lloyds Banking Group chief operating officer Ron van Kemenade said, “Financial crime is becoming more complex and more network‑driven, which means we need to keep pushing the boundaries of technology to protect customers. While quantum computing is still emerging, this experiment has allowed us to translate research into practical insights, while building a strong internal community of quantum experts that will continue to explore future use cases and applications as the technology evolves.”
IBM vice president of quantum adoption and business development Scott Crowder said, “Our collaboration with Lloyds Banking Group demonstrates how forward-looking financial organizations can begin conducting meaningful quantum research. Over the past nine months, Lloyds worked alongside IBM’s quantum computing experts to test how quantum algorithms could help identify patterns within complex transaction networks and combat evolving forms of economic crime. IBM is excited to continue collaborating with financial institutions like Lloyds and further explore how quantum computing could support the future of financial services.”
