Company · Oxford
Oxford Ionics builds trapped-ion quantum computers in which the ions are controlled by electronics on a chip made in standard semiconductor fabs, an approach it calls Electronic Qubit Control. Chris Ballance and Tom Harty founded it in Oxford. In August 2025 it installed QUARTET, a full-stack trapped-ion machine, at the National Quantum Computing Centre under the NQCC testbed programme. IonQ completed its purchase of the company in September 2025 and uses it as a UK base for work with universities and public-sector partners.
Oxford Ionics is an Oxford company. It leads 1 UK project (QUARTET) and is a partner in 7 more. People profiled here include Chris Ballance (Co-Founder and CEO) and Tom Harty (Co-Founder and CTO).
