Quantum Motion is a fast-growing quantum computing scale-up headquartered in London and founded by internationally renowned researchers from University College London and Oxford University with over 40 years’ experience in developing qubits and quantum computing architectures. Bringing together state-of-the-art cryogenic facilities and an outstanding interdisciplinary team, we are developing quantum processors based on industrial-grade silicon chips, with the potential to radically transform computing power in areas such as materials modelling, medicine, artificial intelligence and more.

We are proud to expand our Spanish operations to San Sebastián, Spain, where we are building a state-of-the-art facility in the new CIC nanoGUNE Quantum Tower. This expansion reflects our commitment to driving innovation and collaborating with some of the brightest minds in the quantum industry, and additionally taps into Europe’s strongest semiconductor and cryogenic ecosystem.

Since 2021 our team has been listed every year in the “Top 100 Startups worth watching” in the EE Times, and our technology breakthroughs have been featured in The Telegraph, BBC and the New Statesman. Our founders are internationally renowned researchers from UCL and Oxford University who have pioneered the development of qubits and quantum computing architectures. Our chairman is the co-founder of Cadence and Synopsys, the two leading companies in the area of Electronic Design Automation. We’re backed by a team of top-tier investors including Bosch Ventures, Porsche SE, Sony Innovation Fund, Oxford Sciences Innovations, INKEF Capital and Octopus Ventures, and we have so far raised over £62 million in equity and grant funding.

We bring together the brightest quantum engineers, integrated circuit (IC) engineers, quantum computing theoreticians and software engineers to create a unique, world-leading team, working together closely to maximise our combined expertise. Our collaborative and interdisciplinary culture is an ideal fit for anyone who thrives in a cutting-edge research and development environment focused on tackling big challenges and contributing to the development of scalable quantum computers based on silicon technology.

Our team of 100+ is based in the UK (Oxford and London), Australia (Sydney) and Spain (San Sebastián).

Our mission is global, and Spain is the next chapter in our journey. This is a rare and exciting opportunity to be an employee at a scale-up shaping the future of quantum computing.
