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, which consists of a tileable four-qubit unit cell, was installed under the NQCC’s Quantum Computing Testbed Programme, This is the first system of its kind to use mass-manufacturable 300mm silicon CMOS wafer technology and the first silicon spin-qubit computer to be installed at the Centre.
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. The company’s architecture and manufacturing approach are designed to scale to a fault-tolerant system. The system demonstrates single- and two-qubit operations, initialization, and readout within a compact architecture that has a data-center-friendly footprint of three 19” server racks. This design allows systems to be easily upgraded by installing future generation QPUs.
The delivery is positioned as a step toward building a 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 is also an active performer in DARPA’s QBI program.
