Silicon Quantum Computing Sets New Record with Advanced Quantum Processor

Revolutionizing Quantum Computing with Silicon

In a remarkable step forward for quantum computing, Silicon Quantum Computing (SQC) has established itself as a leader in the silicon modality by unveiling a record-setting quantum processor. This announcement, made on December 17, 2025, illustrates a groundbreaking advancement in the performance of silicon-based quantum technologies.

SQC’s latest multi-qubit, multi-register quantum processor has demonstrated unprecedented levels of fidelity up to 99.99%. Traditionally, as quantum systems expand their qubit count, their performance tends to decline. However, SQC’s innovative architecture exhibits the opposite effect: the quality of qubits significantly improves with increased complexity. This capability is essential for developing fault-tolerant systems that are commercially viable on a large scale.

A Natural Choice for Quantum Computing

The choice to build quantum computers with silicon is strategic. Silicon is not only well-understood within the field of classical computing, but it also leverages extensive investments in research and development, semiconductor fabrication, and wafer purification. SQC distinguishes itself as the only private quantum computing company that produces its own quantum chips (QPUs), ensuring a level of quality and precision previously unseen in the industry.

With over 25 years of dedication to refining its manufacturing processes, SQC achieves atom-level precision, positioning phosphorus atoms within pristine silicon wafers. This meticulous attention to detail demonstrates SQC’s commitment to materials purity and precise engineering—fundamental elements in reaching the goal of commercial-scale quantum computing.

Leading the Charge in Quantum Algorithms

SQC has consistently excelled in delivering world-class accuracy in benchmark quantum algorithms, such as Grover's algorithm. The recent results across multiple registers pave the way for scaling towards millions of qubits.

SQC's CEO, Michelle Simmons, remarked on this groundbreaking achievement, stating, "In most quantum systems, scale comes at the cost of performance. Our system increases in quality as it scales, an immense accomplishment that reflects our careful choices in materials and architecture. We are on track to deliver the world's first commercial-scale quantum computer." This ambitious remark demonstrates SQC's confidence in its technology and future potential.

Strategic Partnerships and Future Outlook

SQC’s Chair, Simon Segars, who is also a former CEO of ARM, underscores the elegance of SQC’s approach to quantum computing. He emphasizes that together with partners and customers, SQC is already delivering tangible value in quantum computing. The recent progression to Stage B of DARPA's Quantum Benchmarking Initiative marks a significant milestone for the company. SQC's technologies are making a tangible impact: Telstra has reported significant reductions in model training times using SQC's quantum machine learning systems, while Australian Defence has made a commitment to deploy a rack-mounted system within its data center environments.

In summary, Silicon Quantum Computing is not only advancing quantum technology but is also creating practical solutions for real-world applications. As SQC continues to innovate and refine its quantum capabilities, the future of quantum computing looks incredibly promising and poised for transformative breakthroughs in various fields.
