Two doctoral students at Oxford stood in front of the same stubborn machine more than ten years before either of them ran a company.
Chris Ballance and Tom Harty met during their PhDs in trapped-ion physics. The ions themselves were beautiful, the best qubits anyone had. The problem was everything around them. The control systems were bulky, hand-built and wildly hard to scale. A machine that worked in a lab could not become a product.
Early backing came from Oxford Science Enterprises, followed by external rounds.
They did not leave. Both stayed in the field and, in 2019, founded Oxford Ionics. Ballance later described them as two physicists with a strong conviction that the technology had untapped potential. Conviction is what a founder has before there is evidence.
The stakes were plain. A quantum startup spends years burning money on hardware before it can show a customer anything, and bigger names like IBM and Google had a head start. Early backing came from Oxford Science Enterprises, followed by external rounds. The sources read for this profile do not give amounts or the lowest points, so those are left out rather than guessed.
What almost nobody outside the field understood was the idea itself. Rather than taming the control hardware, they chose to replace it, using conventional silicon chip technology to run the ions. If it worked, a quantum computer could be built with the same factories that make ordinary chips.
It worked well enough to attract a buyer. On 9 June 2025, US-listed IonQ announced a $1.075bn deal for Oxford Ionics, paid as $1.065bn in IonQ shares and $10m in cash. The deal completed in September 2025 and the University of Oxford calls it the highest-value acquisition of any of its quantum spinouts. The team is expected to keep working in the UK.
There is a cost hiding in that price. A British deep-tech company, built over six years on a university's research, now sits inside an American one.
The quiet lesson is in how it started. The founders did not meet at an accelerator. They met at a lab bench, spent a decade learning what was broken, and only then decided it was fixable.
