Quantum Motion

A London company, spun out of University College London and Oxford, that builds quantum computers from silicon chips made in standard factories.

About Quantum Motion

Quantum Motion builds quantum computers out of silicon, the same material in the chips inside your phone. Its qubits, the quantum equivalent of bits, are single electrons trapped in tiny structures called quantum dots, and their spin is used to store information. Because the chips can be made on standard 300 millimetre wafers in existing semiconductor factories, the company hopes to make quantum processors with millions of qubits at a reasonable cost. In September 2025 it announced what it called the industry's first full-stack quantum computer built using standard silicon manufacturing, installed at the UK's National Quantum Computing Centre (NQCC), and fitting in three server racks.

The company was founded in 2017 by researchers from Oxford University and University College London. Chief executive Dr James Palles-Dimmock called the launch 'quantum computing's silicon moment', and president and chief commercial officer Hugo Saleh described a customer, user and developer first approach. The company's stated mission is to deliver fast, fault-tolerant quantum computing in a 'box, not a building', with uses in drug discovery, materials science and finance.

Quantum Motion is based in London, and its system is hosted at the NQCC on the Harwell campus in Oxfordshire. It also has offices abroad: it has staff in the United States, Australia and Spain, including an office in San Sebastian. Reports from 2026 put the company at over 120 people, up from roughly 30 in 2022. That growth means plenty of new roles, from chip design to software. It is also part of SiQEC, a UK-funded project to demonstrate error-corrected silicon quantum computing, and takes part in the US DARPA Quantum Benchmarking Initiative.

The company says its staff include integrated circuit engineers, quantum theorists and hardware specialists. Job listings we saw advertise posts such as senior quantum engineer, research software engineer and a lead engineer for advanced chip packaging. We did not find first-hand descriptions of the working culture, so we cannot say what day-to-day life is like.

It is a good example of how a university research idea becomes real hardware. If you enjoy physics, electronics, materials or computer science, the work spans all of them, from how a single electron behaves to how racks of control electronics connect to a chip. The company's website lists what is open now.
