15 Companies in the United Kingdom Making Waves with Quantum Technologies

We’ve widened our information set to include Quantum related companies too (not just quantum computing) – some of those companies are funding the very Quantum Start-ups that we write about. Other such as Oxford Instruments, as their name suggests provide some of the refrigeration technologies that allow the super cool Qubits to operate.

We have to caveat that with private companies, despite research efforts it is often not possible to accurately determine some attributes as this information is privately held.

About the Data

We will not be held liable for the accuracy of this data. Much of these data are hidden from public view and change very frequently. Should you feel that any of the numbers or data are totally wrong please reach out to us, or if you would like to update the data of your organisation.

We categorise companies into Fledgling, Growth, Unicorn and Enterprise. Fledgling means that the company is fairly small and is typically in its infancy and development. Growth companies those that are steadily increasing their revenues, offering and traction in the marketplace. Unicorn companies are those companies which has gotten to the stage where they are valued at or around a billion dollars. Enterprise companies are larger more established firms which may or may not be listed entities on public markets (think IBM, Microsoft, Amazon etc).

The sector covers the businesses areas that the company operates in. We cover Quantum Computing, Quantum Communications (Networking, Internet), Quantum Sensors and Research and more.

The function is where the production of the business is captured: from building software to hardware or to making investment or providing education.
