TreQ

A quantum engineering company with its headquarters and production site at Milton Park, Oxfordshire, building upgradeable quantum computing clusters.

About TreQ

TreQ designs and builds quantum computing systems for businesses, institutions and communities. Its idea is to build custom 'open-architecture' clusters, meaning arrangements of quantum computers made so that parts can be upgraded over time. The company says this protects customers from buying equipment that is out of date within a few years, which is a real worry in a field changing as quickly as quantum. It describes itself as a quantum engineering and manufacturing company, so its work is about building and running machines as well as designing them.

TreQ was founded by Mandy Birch, who is its chief executive. She is a brigadier general in the United States Air Force Reserve and an adviser to the UK's National Quantum Computing Centre. The company's stated aim is to lower the barriers to using quantum computing by tackling cost, inefficiency and the pace at which technology becomes obsolete. A February 2025 report says its team has held senior roles at Rigetti Computing, NASA, Apple and Cisco, and has between them built several quantum computers, including the UK's first commercial quantum computer.

The company opened its headquarters and production site at the Milton Park Innovation Centre in Oxfordshire in 2025, and says its core engineering team is based in the UK even though its approach is global. It planned to put its first quantum computing system into operation in 2025, but the report we read is from February 2025 and we did not find later news, so we cannot confirm whether that happened. We found no headcount.

The article tells us little about daily culture. What it does show is a company set up by people who have already built machines, who describe themselves as practical engineers rather than researchers. Being at Milton Park puts the team in one of the main science and technology parks in the UK, close to the Harwell quantum cluster, though we did not find a statement from the company about its working life.

Jobs at a company that builds and runs quantum systems include quantum and hardware engineers, cryogenic and electronics specialists, software and control engineers, manufacturing and test technicians, and project, operations and commercial staff. Physics, engineering, computing and manufacturing backgrounds are the usual routes. Look at the company's website for roles. The pages we read did not name individual UK staff beyond the founder, so the best way to learn who works there is through the company's own updates.
