London-based Quantum Motion Technologies Ltd. has achieved a significant milestone in quantum computing by unveiling the world’s first quantum computer utilizing conventional semiconductor manufacturing techniques. This innovative system is now operational at the UK National Quantum Computing Centre, a facility aimed at propelling quantum computing advancements.
This groundbreaking machine employs 300-millimeter silicon wafers, making it the initial spin-qubit computer integrated into the center’s quantum computing testbed program. By leveraging complementary metal-oxide-semiconductor (CMOS) technology, widely used across consumer and enterprise devices, Quantum Motion demonstrates the feasibility of producing a robust quantum computer using familiar, scalable methods.
James Palles-Dimmock, CEO of Quantum Motion, emphasized the importance of this launch, stating, “This is quantum computing’s silicon moment.” He outlined that the new computer not only represents a leap in technology but is also designed for mass production capabilities suited to existing data centers. The compact system, approximately the size of three 19-inch server racks, is engineered for easy integration, leaving space for significant upgrades to its quantum processing unit without expanding its footprint.
The architecture of the computer features a scalable tile design, incorporating compute, readout, and control components that can be efficiently replicated on a chip. This design approach allows for mass production and the potential to scale up to millions of qubits per quantum processing unit (QPU). Unlike traditional bits in classical computing, qubits can exist in multiple states simultaneously, enabling quantum computers to execute highly complex calculations much faster than classical systems.
The implications of this technology stretch across various fields, including healthcare, where it may accelerate drug discovery, and in clean energy by optimizing energy distribution. U.K. Science Minister Lord Vallance noted that this development moves quantum computing closer to commercial feasibility, with potential substantial benefits for society.
In addition to Quantum Motion, other companies are also exploring silicon-based quantum processors. SemiQon Technology Oy from Finland has recently made strides in this space, successfully demonstrating a cryogenically optimized CMOS transistor to enhance quantum dot qubit efficiency.
Furthering its initiatives, Quantum Motion has also been awarded the Silicon Quantum Error Correction project, aimed at creating a quantum computing system with high fault tolerance. This collaboration with University College London aspires to achieve 1 trillion quantum operations in error-corrected systems by 2035, marking another step in the evolution of quantum technology.
