A UK startup has made a revolutionary advancement after delivering the world’s first full-stack quantum computer, built using the same silicon chip technology found in smartphones and laptops.

London-based Quantum Motion, a quantum computing startup that develops scalable quantum computing tech using silicon, launched the industry’s first full-stack quantum computer made with silicon. It was deployed at the UK National Quantum Computing Centre (NQCC).

This is reportedly the first quantum computer to be built using the standard complementary metal-oxide-semiconductor (CMOS) chip fabrication process which is the same transistor technology used in conventional computers.

A key part of this approach is building cryoelectronics that connect qubits with control circuits that work at very low temperatures, making it possible to scale up quantum processors greatly.

“This is quantum computing’s silicon moment,” James Palles‑Dimmock, Quantum Motion’s CEO, stated. “Today’s announcement demonstrates you can build a robust, functional quantum computer using the world’s most scalable technology, which can be mass-produced.”

Built for mass production

The system combines the company’s Quantum Processing Unit (QPU) with a user interface and control stack that supports industry-standard frameworks such as Qiskit and Cirq, making it a full-stack quantum computing solution.

What’s more, it also features a data center–friendly footprint that occupies just three 19-inch server racks that house the dilution refrigerator and integrated control electronics.

“The NQCC is accelerating UK quantum capabilities by evaluating several diverse hardware platforms by leading companies worldwide,” Michael Cuthbert, PhD, NQCC’s director, explained.

The auxiliary equipment operates separately from the main system, which enables easy integration into standard data center environments. This modular setup supports upgrades to significantly larger QPUs without changing the system’s physical footprint.

Cuthbert stated that installing the system greatly advances the NQCC’s quantum computing testbeds initiative. “The NQCC team is really excited to start testing and validation of the system and better understand how real-world applications will map onto its silicon architecture,” he said.

Tested in real conditions

In contrast to other quantum computing approaches, the startup used high-volume industrial 300 millimeter chipmaking processes from commercial foundries to produce qubits.

The architecture, control stack, and manufacturing approach are all built to scale to host millions of qubits and pave the way for fault-tolerant, utility-scale, and commercially viable quantum computing.

“With the delivery of this system, Quantum Motion is on track to bring commercially useful quantum computers to market this decade,” Hugo Saleh, Quantum Motion’s CEO and president, revealed.

The system’s underlying QPU is built on a tile-based architecture, integrating all compute, readout, and control components into a dense, repeatable array. This design enables future expansion to millions of qubits per chip, with no changes to the system’s physical footprint.

According to Quantum Motion, the system represents a breakthrough in AI machine‑learning tuning, enabling more efficient operation and automated algorithms for control and calibration.

“It’s a customer, user, and developer first approach – using standard CMOS, the basis for all modern technology, from mobile phones to AI GPUs, to deliver the revolutionary next inflection point in computing,” Saleh concluded in a press release.
