Quantum Motion, a UK-based quantum company, has delivered a full-stack quantum computer built using a standard silicon CMOS chip fabrication process to the UK National Quantum Computing Centre (NQCC). The system, installed under the NQCC’s Quantum Computing Testbed Programme, is the first to use mass-manufacturable 300mm silicon CMOS wafer technology and the first silicon spin-qubit computer to be installed at the Centre. The qubit count of the processor was not disclosed in the press release.
The system integrates a Quantum Processing Unit (QPU) with a user interface and control stack compatible with industry standard software frameworks such as Qiskit and Cirq. With a data-center-friendly footprint of three 19” server racks, the system houses a dilution refrigerator and integrated control electronics. The QPU is based on a scalable tile architecture designed to enable expansion to millions of qubits per QPU. This design allows systems to be easily upgraded by installing future generation QPUs.
The delivery is positioned as a step toward building a robust, functional quantum computer using scalable technology with the ability to be mass-produced. The installation is part of the NQCC’s program to evaluate diverse hardware platforms and support research into how real-world applications will map onto its silicon architecture. Quantum Motion’s architecture and manufacturing approach are designed to scale to a fault-tolerant system, and the company is also an active performer in DARPA’s QBI program.
