Quantum computing firm Oxford Quantum Circuits (OQC) has appointed Gerald Mullally as its permanent CEO, following 14 months in the role on an interim basis.
Mullally officially steps into the position with the backing of OQC’s board of directors after leading the company through a pivotal phase of growth, innovation and international expansion.
Under his leadership, the Reading-based firm launched its Dimon qubit technology, expanded into the US with the first-ever quantum computer in New York City and secured key partnerships across government and industry.
He also oversaw the company’s $100m Series B investment round, backed by major global players including Chevron and Sumitomo Mitsui Trust Bank.
“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.
“His leadership has brought strategic focus to the business and aligned our scientific breakthroughs with long-term growth.”
Since stepping in as interim CEO in June 2024, Mullally has driven a number of strategic milestones, including the first integration of a quantum computer into a commercial data centre and the UK’s first quantum error correction testbed.
He brings over 20 years of experience spanning both the public and private sectors, having previously held senior leadership roles at Accenture and PwC, advising clients across technology, finance, energy and defence.
He also served for eight years in the UK Prime Minister’s Office and Cabinet Office, where he led national security and technology policy.
“Leading OQC is a tremendous honour,” said Mullally. “We are not only building a world-class quantum company — we’re shaping a new global industry.
“I’m proud to work with such talented people to realise the profound potential of our core architecture and deliver commercial impact at scale.”
