Oxford Quantum Circuits has added former HSBC chief executive Colin Bell to its recent string of appointments, with the banking veteran joining the company’s board.
Bell, a former British Army officer, has spent almost two decades as a senior executive in banking and finance, having held prominent roles at Barclays and UBS before joining HSBC as its head of financial crime risk in 2016 and eventually advancing to the top job in 2021, where he remained until January of this year.
Though not a sector that immediately brings to mind advanced computing and deep tech, finance has had a surprisingly significant role in the quantum sector in recent years.
Reporting from UKTN in April found that in 2025, banks were responsible for as many as one in ten quantum patent applications in the UK.
Furthermore, according to banking insights firm Evident AI, almost 80% of the 50 major banks tracked by the group were in some way involved with quantum, which includes hiring roles with quantum expertise, commissioning research, investing or applying for patents.
There is particular interest in the technology’s potential for scaling the security of banking systems as well as the potential for advanced modelling produced by the machines.
Recognising the increasing relevance of quantum computing to banking and finance, Oxford Quantum Circuits has brought on Bell, who can apply his extensive experience in banking, compliance and financial crime to the firm as it looks to secure business in the sector.
Bell also brings with him experience in defence through his 16 years of military service.
“I’m delighted to welcome Colin Bell to the OQC board. He brings a rare combination of leadership across global finance, defence, and operational risk – experience that aligns directly with our mission,” said board chair Jack Boyer.
“His appointment further strengthens the Board as we scale quantum computing in sectors where trust, resilience, and performance are critical to success.”
Bell has also held appointments from the Ministry of Defence (MoD) and NATO.
“OQC stands out for its clarity of vision in bringing quantum computing to sectors where security, resilience, and performance are critical,” said Bell.
“With world-class technology and scientific depth, the company is uniquely positioned to lead this transformation. I’m excited to join the board at this pivotal moment and support OQC’s next phase of growth and global scale.”
The appointment follows several recent senior hires to the company, including Robert Coutts as CFO announced last week, former Cabinet Office director Gerald Mullally as chief executive in July and Boyer’s appointment in April.
