Silicon Quantum Computing (SQC) has achieved a breakthrough in quantum processing, demonstrating a multi-qubit, multi-register processor with record-setting fidelity. Published in Nature, SQC’s silicon-based quantum processor attained fidelities up to 99.99%, establishing leadership in the scalable silicon modality of quantum computing. Notably, this architecture improves qubit quality as qubit count increases—a critical advancement for fault tolerant, commercial scale systems. SQC is unique as the only private company manufacturing its own quantum chips using a 25-year-developed process achieving 0.13 nanometer precision. SQC’s Advances in Silicon Quantum Computing Silicon Quantum Computing (SQC) has established itself as a leader in silicon-based quantum computing with a record-setting processor. This breakthrough differs from typical quantum systems where adding qubits diminishes quality; SQC’s architecture improves qubit quality as qubit count increases – a crucial step towards building fault-tolerant, commercial-scale systems. Published in Nature, this multi-qubit, multi-register processor demonstrates exceptional performance, achieving fidelities up to 99.99%. SQC uniquely manufactures its own quantum processing units (QPUs) using a highly refined, 25-year-developed process. This allows for atom-level precision, patterning chips with 0.13 nanometer accuracy by strategically placing phosphorus atoms within pure silicon wafers. Leveraging existing silicon manufacturing infrastructure – including trillions of dollars in R&D and fabrication – provides a significant advantage in scalability and cost-effectiveness for building larger quantum computers. This advancement isn’t just theoretical; SQC is already delivering commercial value. Telstra experienced reductions in model training time using SQC’s quantum machine learning systems, and Australian Defence has deployed a rack-mounted system. SQC’s ability to design, produce, and test new systems weekly, combined with consistent, world-leading accuracy on benchmarks like Grover’s algorithm, signifies a clear path towards scaling to millions of qubits.
Achieving High Qubit Quality and Scalability Silicon Quantum Computing (SQC) has achieved a breakthrough in qubit quality and scalability, demonstrating increasing performance as qubit count increases. This is significant because typical quantum systems see quality decline with added complexity. SQC’s processor achieved fidelities up to 99.99%, setting a new milestone and clearing a path towards fault-tolerant, commercial-scale systems. This advancement is enabled by their silicon-based approach, leveraging decades of existing R&D in semiconductor manufacturing. SQC manufactures its own quantum processing units (QPUs) with exceptional precision, patterning chips at the atomic level—0.13 nanometers. This industry-leading manufacturing process, developed over 25 years, utilizes pure silicon wafers and precisely placed phosphorus atoms. This level of control is crucial for maintaining high qubit quality, and positions SQC uniquely to rapidly design, produce, and test new quantum systems on a weekly basis. The company’s success is already impacting industries; Telstra reported reductions in model training time using SQC’s quantum machine learning systems, and Australian Defence has deployed a rack-mounted system. SQC’s architecture is designed to scale towards millions of qubits, and the recent results across multiple registers indicate that this path is now clear, suggesting a viable route to a commercial-scale quantum computer. SQC’s Manufacturing and Commercial Progress Silicon Quantum Computing (SQC) has established itself as a leader in silicon-based quantum computing with a record-setting processor. Notably, SQC’s architecture demonstrates increasing qubit quality as qubit count increases—a critical step toward building fault-tolerant, commercial-scale systems. This achievement breaks the typical trend where adding more qubits decreases system quality, and has been published in Nature. SQC uniquely manufactures its own quantum chips (QPUs) using a highly refined 25-year-old process. SQC’s manufacturing process achieves 0.13 nanometer precision—atom-level accuracy—when placing phosphorus atoms within pure silicon wafers. This capability leverages decades of silicon R&D and fabrication techniques, representing trillions of dollars in prior investment. The company’s ability to control its own QPU manufacturing enables rapid design, production, and testing of new systems weekly, and delivery of quantum machine learning systems to customers. SQC is already demonstrating commercial momentum, progressing to Stage B of DARPA’s Quantum Benchmarking Initiative. Furthermore, Telstra has reported reductions in model training time using SQC’s quantum machine learning systems, and Australian Defence has purchased a rack-mounted system for datacenter deployment. SQC’s founder emphasizes the system’s increasing quality with scale, positioning the company to deliver the world’s first commercial-scale quantum computer. Typically, when quantum systems add more qubits and become more complex, their quality declines. SQC’s architecture demonstrates the opposite: as qubit count increases, the qubit quality strengthens – a critical requirement for fault tolerant, commercial scale systems.
