SQC, an Australian company, is a quantum computing firm specializing in manufacturing high-quality qubits and processors using silicon and phosphorus atoms as its core materials. It champions the use of "natural qubits" (using only silicon and phosphorus atoms) to achieve the "highest algorithmic fidelity" in processor performance. The company's core products include quantum processors (in a silicon-phosphorus material system) and a fully in-house chip manufacturing and rapid iteration process. It is also developing analog and error-corrected processors, while offering commercial products for quantum machine learning and cloud access.
Technology and R&D
Materials and Qubit Design: Constructs quantum processors using just two types of atoms, silicon (Si) and phosphorus (P), focusing on the simplicity and high fidelity of the material system.
Integrated Manufacturing: Fully in-house chip fabrication, with co-development of tools and processes to accelerate design, validation, and integration in parallel.
Computational Roadmap: Simultaneously developing analog simulation and gate-based processors, with error correction as a long-term goal.
R&D Output: Over 200 patents and 250 journal publications, demonstrating continuous technological accumulation.
