READING, UK – 28 July 2025 – Oxford Quantum Circuits (OQC) today confirmed the appointment of Gerald Mullally as chief executive officer.
Mullally has served as interim CEO since June 2024 and now assumes the role permanently, following approval by the Board of Directors.
The company said Mullally’s appointment follows a period of growth under his leadership during which OQC expanded its international footprint, launched its Dimon qubit technology and secured strategic partnerships across government and enterprise.
“Gerald has led OQC with clarity, integrity and conviction over the past 14 months, guiding the company through a critical phase of development,” said Dr Peter Leek, Founder and Chief Science Officer of OQC. “His leadership has brought strategic focus to the business and aligned our scientific breakthroughs with long-term growth.”
“Gerald has provided strong leadership through a period of rapid growth and innovation,” said Jack Boyer OBE, Chair of OQC’s Board of Directors. “He is the right leader to take OQC forward as the company shapes the future of quantum computing on the global stage.”
Mullally has shaped OQC’s commercial direction with a focus on high-impact, mission-aligned markets – including security, defence, and finance. He has overseen international expansion and helped position OQC as a trusted quantum partner to both government and industry.
As interim CEO, he oversaw a series of milestones, including:
- The launch of OQC’s public roadmap, establishing a leadership position in the global race for quantum computing.
- The introduction of the OQC Dimon, a dual-rail qubit architecture designed for speed, scale, and quality.
- Strategic growth in financial services, security and defence as the first sectors to realise quantum advantage.
- Expansion into the United States, with the first-ever quantum computer to be deployed in New York City to deliver low-latency quantum compute directly to Wall Street.
- A successful Series B investment round, backed by leading global investors including Chevron and Sumitomo Mitsui Trust Bank.
- The launch of the UK’s first quantum error correction testbed and the world’s first integration into a commercial data centre.
Together, these achievements reflect Gerald’s ability to translate vision into execution, advancing OQC’s leadership across technology, markets, and infrastructure.
Mullally brings two decades of cross-sector leadership experience to his role as CEO. He has led strategy and technology initiatives across financial services, security, defence and energy, during his time at Accenture and PwC.
Alongside his commercial background, Gerald spent eight years as a senior official in the UK Prime Minister’s Office and Cabinet Office, where he worked on national security issues.
