Quantum Motion at NQCC
Quantum Motion at NQCC is a silicon spin quantum computer operated by National Quantum Computing Centre in United Kingdom. Its physical qubit count has not been published. 8 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as Quantum Motion full-stack silicon CMOS system
Quantum Motion's full-stack silicon CMOS quantum computer delivered to the NQCC in September 2025, the first silicon spin-qubit machine installed under the NQCC testbed programme. It uses Qiskit- and Cirq-compatible software. The qubit count and fidelities were not stated in the source consulted, so none are recorded.
Spec sheet
Technical details as the builder or a paper states them, each with its own source. A blank is a fact we could not source, not a zero. Fidelity and coherence figures are in the benchmark table below.
| Spec | Value | Basis | Note | Source |
|---|---|---|---|---|
| Processor | Silicon spin-qubit CMOS QPU, tile architecture | Vendor reported | No chip name or qubit count was published in the September 2025 delivery announcement. | thequantuminsider.comquantumcomputingreport.com |
| Qubit type | Silicon spin qubit in CMOS | Vendor reported | Quantum Motion describes its approach as silicon-spin technology built with standard silicon processing. | thequantuminsider.comquantummotion.com |
| Topology | Tile architecture built from a tileable four-qubit unit cell | Vendor reported | Each tile integrates compute, readout and control and is repeatedly printed across the chip. | quantumcomputingreport.comelectronicspecifier.com |
| Cooling and environment | Dilution refrigerator housed within the three-rack system | Vendor reported | The three 19-inch racks hold the dilution refrigerator and control electronics, with auxiliary equipment positioned separately. | thequantuminsider.comelectronicspecifier.com |
| Fabrication | 300 mm silicon CMOS wafers at commercial chip foundries | Vendor reported | The company site lists GlobalFoundries among its fabrication partners but the delivery announcement does not name the foundry for this chip. | thequantuminsider.comquantummotion.com |
| Software | Qiskit and Cirq compatible control stack | Vendor reported | Announced as an integrated control stack and user interface compatible with industry standard frameworks. | thequantuminsider.comquantumcomputingreport.com |
| Access and pricing | On-premises testbed system at the UK NQCC, Harwell | Vendor reported | Installed under the NQCC Quantum Computing Testbed Programme in September 2025 as its first silicon spin-qubit machine; no price published. | thequantuminsider.comquantumcomputingreport.com |
| Roadmap | Tile architecture designed to scale to millions of qubits per QPU, with QPU swap-in upgrades | Vendor reported | Stated on 15 September 2025; the three-rack footprint is meant to host future larger QPU generations. | thequantuminsider.comquantumcomputingreport.com |
