Before a quantum processor can compute, each qubit has to be characterised and tuned, work that experts do by hand. QuantrolOx, co-founded by the physicists Andrew Briggs and Natalia Ares with chief executive Vishal Chatrath, sells machine-learning software to automate it. The company is headquartered in Espoo, Finland, with offices in Oxford, Delft and Bengaluru, according to its website.
The European Innovation Council granted €2,495,500 towards a €3.6 million project from April 2023 to September 2025. The final report says it launched Quantum EDGE "for automation of qubit bring up, characterization, testing and tune up", supporting three superconducting qubit architectures, and that one case study cut chip characterisation "from 14 days to less than a day". In September 2025 the software was installed at the UK's National Quantum Computing Centre. QuantrolOx Finland Oy reported revenue of €82,000 in 2024, an operating loss of €2.55 million and an equity ratio of minus 301%, according to Asiakastieto.

Where QuantrolOx Stands Now
Since 2025 QuantrolOx has announced a development kit with QuantWare, a lab system with TreQ, a training programme and letter of intent with India's C-DAC, the Quantum EDGE-powered hub at Manipal Academy of Higher Education, and a partnership with Aqsolotl in June 2026, according to its news. It has not announced a funding round since its £1.4 million seed round in February 2022.
"We're pleased that NQCC researchers are making use of Quantum EDGE in their experimental set-ups."
Vishal Chatrath, CEO, QuantrolOx, September 2025The Technology: Machine Learning at the Qubit
According to the report, Quantum EDGE offers automated bring-up workflows and interfaces to major control electronics makers. The report says it completed a full tune-up "in less than 10 minutes with a single click", which it calls a speed-up of two orders of magnitude. The figures come from the company's own case studies.
What the EIC Project Promised, and What CORDIS Shows
The project set out to automate quantum control with machine learning. It delivered a released product, a user interface for monitoring processors and automated workflows across three qubit architectures. The report does not give customer numbers or revenue. CORDIS still lists the project as signed.

The Money
The Finnish company's operating losses were €985,000 in 2022, €2.26 million in 2023 and €2.55 million in 2024, as staff grew from 5 to 17. Its equity was negative at the end of 2024. The accounts of its UK, Dutch and Indian companies are not included, and the size of any EIC equity investment has not been disclosed.
What Cannot Be Checked
Questions for the EIC
The group's total revenue, how the Finnish company is funded with negative equity, whether the equity part of the blended award was invested, and how many paying customers use Quantum EDGE are not public.
Why Europe Should Care
The EIC report calls manual qubit tuning a major bottleneck in quantum processor development. The EIC funded a European company to build it, and research centres use it. Revenue has not followed at any scale.
What the project promised
Machine-learning software to automate the control of quantum processors.
What the record shows
A launched product used at research centres, €82,000 in 2024 revenue and negative equity in the Finnish company.
The Verdict
A tool with users, not yet a business
QuantrolOx built what the EIC paid for and placed it in serious labs. Its Finnish accounts show a company still far from paying its way.
