Scientists unveil world’s first quantum computer built with regular silicon chips
A British startup has created the first silicon -based quantum computer in the world made using the same transistor technology found in almost all modern digital electronics.
The machine is built using the complementary metal oxide manufacturing process (CMOS) – the same is true to create chips for devices such as smartphones, laptops and digital cameras.
Another important element of the machine, built by the quantum movement of society, is its relatively low imprint. The machine can be housed in only three 19-inch serving holders, including the dilution refrigerator and the integrated control electronics which handles the quit And produce the extremely low temperatures necessary to maintain their fragile quantum states.
The system combines a Quantum processing unit (QPU) with a user interface and standard control software in the industry – the specialized layer which acts as the interpreter between a high -level quantum program (algorithm) and physical quantum equipment (qubits), such as Qiskit and CIRQ – to provide a complete quantum calculation platform. It uses spin qubits – a type of qubit which codes for quantum information in the spin (intrinsic angular moment) of an elementary particle, most often a single electron.
They are also very scalable quantum movement representatives declared on September 15 in a statement. The QPU itself is based on the architecture of tiles – a modular design approach where a processor or a system on a chip (SOC) is built from smaller, autonomous and specialized units called tiles or chiplets.
The QPU condenses the necessary calculation, reading and control elements in a single dense table which can be deployed several times on a single chip. This means that future QPU iterations, the physical equipment where quantum calculation occurs, can be upgraded to include millions of qubits, have declared representatives, and the system could allow future versions of the company QPU to be easily exchanged by the existing processor.
“This is the moment of quantum computing silicon,” said James Palle-DimmockCEO of quantum motion. “Today’s announcement shows that you can create a robust functional quantum computer using the most scalable technology in the world, with the possibility of being produced in series.”

Quantum movement representatives claim that this system is the first step to provide commercially viable quantum computers during the decade.
The system is currently deployed to the UK National Quantum Computing Center (NQCC) – a national laboratory for quantum computer science, mainly funded within the framework of the UK Research and Innovation (UKRI) program.

The Quantum Motion system also represents the first computer in spin-qued silicon developed under the Auspices of NQCC Quantum calculation test bed programAn initiative to build seven prototypes of quantum computers using different technologies and to test their viability.
The computer relies on research Built by Quantum Motion in collaboration with University College London (UCL) to create more quantum systems tolerant with breakdowns. This research has demonstrated 98% precision in the doors of two qubit, the fundamental construction block of a quantum circuit. It is a peak mark in qubits made in natural silicon on a 300 mm brochure scale, the same material used in the new computer.
Defect tolerance is essential to quantum computers because the qubits are notoriously fragile and subject to errors. The instability is due to a property called decoherence.
The superimposition (the capacity of a QUBIT exists in several states at the same time) and the entanglement (the capacity of two or more qubits to be connected to each other and to share the same state at any distance, so that the modification of one modifies the other simultaneously), the keys to quantum calculation, are both fragile states which can be destroyed by the greatest interaction with the environment.
Temperature changes, electromagnetic interference or other environmental factors can deform or collapse these properties, leading to inaccurate results. This fragility is one of the greatest obstacles to evolving and powerful quantum computer science. This is why a lot of research on quantum computer science is in the field of Quantum error correction (QEC).
As part of SIQECON SILICON quantum error correction projectThe quantum patterns take advantage of silicon spin qubine qubits created using standard semiconductor manufacturing processes of 300 mm and its research on the correction of errors to build quantum advantage.
The main edge that this type of manufacture is on other processes is the community of silicon manufacturing. Since the installations, standards and effective production techniques of these chips are already well established, they can be produced at a lower cost, quickly and on a larger scale than other more specialized components.
