About Us

"I find it incredible that just 50 atoms can out-perform room-sized supercomputers. I've seen this go from ludicrous to possible to within our reach. We can achieve this amazing feat by following nature’s lead, not fighting it; we are embracing the counter intuitive behaviour of the quantum world to achieve things that we can only dream about today."


Chris Ballance, Co-Founder & CTO

Our Founders

Tom Harty and Chris Ballance founded Oxford Ionics in 2019 after over a decade spent working together at the frontier of Quantum Computing. Building on four decades of leadership at Oxford University, Oxford Ionics is unlocking the power of the quantum world to transform the way we compute.

Dr. Chris Ballance

Chris is a world leader in the field of Ion Trap Quantum Computing with a DPhil in the area from Oxford University, where he is also a Future Leaders Fellow. His work on trapped ion technology and how we can manipulate these qubits at sufficient scale, and with sufficient precision, to build useful quantum computers, is the basis for Oxford Ionics and the pioneering research he carries out continues to shape the direction of the company.

Dr. Tom Harty

Tom holds the world record for the most precise quantum gate ever performed. Before founding Oxford Ionics, he was a Senior Researcher at Oxford University where he completed his PhD in Atomic and Laser physics.

His passion for bringing technology to market lead to him co-founding Oxford Ionics and becoming CEO in 2019. He was elected a SME Leader by the Royal Academy of Engineering in 2021 in recognition of his work at Oxford Ionics.

The Technology

We build quantum computers using flawless atomic qubits: ions trapped above the surface of a microchip. Combining the best of photonic and microwave technology allows us to manipulate these qubits with negligible noise and unmatched reliability.


We take scalability seriously, developing the capability to control interconnected qubit registers in parallel and without compromising performance. We are creating the first systems that deliver tangible computational benefits for real-world problems.
