QuantrolOx is a software company specializing in quantum technology that accelerates the development of quantum computers toward practical applications. The company’s software solves a key challenge in scaling quantum computing.
QuantrolOx is a spinout from the Ares Lab at the University of Oxford and helps research institutions and industry speed up the future of quantum computers. The company focuses on removing a key technical barrier that has prevented the realization of practical quantum computers.
The building blocks of quantum computers, qubits, are sensitive to environmental disturbances. Even a small disturbance can cause problems in calculations, and controlling qubits has therefore required constant fine-tuning. This approach does not scale as the number of qubits increases. The tuning process quickly becomes so slow and labor-intensive that only a fraction of the potential computational power of quantum computing can be utilized.
The Quantum EDGE software automates this fine-tuning. A task that previously took several PhD-level experts up to a week can now be completed with Quantum EDGE in under 25 minutes at the push of a button.
Quantum computing is expected to first impact four sectors: the chemical industry, life sciences, finance, and mobility. The market potential is estimated to reach as much as $2 trillion by 2035.
QuantrolOx is also on a fast growth trajectory. The company began selling to customers in 2024 and increased its sales that year to €154,000. In 2025, sales are expected to grow to around €2 million and revenue to €1 million, and by 2030 revenue is expected to reach €92 million.
Since its founding, QuantrolOx has raised a total of €10.9 million in equity financing through shares and convertible notes. Its largest investors include Nielsen Ventures, 2xN, Voima Ventures, Hoxton Ventures, Serendipity Capital, and Oxford Science Enterprise.
