UK-based Quantum Motion has installed the world’s first full-stack quantum computer, built entirely with silicon chip technology and fitting into three server racks, at the NQCC and has begun testing.

UK-based Quantum Motion has unveiled the world’s first full-stack quantum computer developed with the same silicon technology used in everyday devices. The system, which fits into three 19-inch server racks, has been installed at the UK’s National Quantum Computing Centre (NQCC).

Developed using a standard CMOS manufacturing process, the machine can be produced in commercial chip fabrication plants and integrated into existing data center infrastructure. The company describes this step as the “silicon moment of quantum computing.”

Technical Details Remain Unspecified

Launched in 2017 as a spin-out from University College London and Oxford University, Quantum Motion’s solution takes a different approach from the commonly used superconducting or photonic systems of today. The device is built on a silicon-based spin-qubit processor and features a scalable, modular architecture.

The company states that the entire stack, including the cryogenic and control systems, fits into three standard 19-inch racks. It also supports existing software frameworks like Qiskit and Cirq, allowing developers to easily adapt to the ecosystem.

However, details about the system’s performance have not yet been shared. The qubit count, error rates, coherence times, and initial test results have not been disclosed. Furthermore, no information has been provided on critical quantum computing topics such as error correction and connectivity scaling.

Traditional quantum machines are often the size of a refrigerator and require specialized infrastructure. What sets Quantum Motion apart is its ability to deliver a complete quantum stack using entirely standard silicon technology for the first time, and fitting it into a data-center-compatible form factor.
