Silicon Quantum Computing (SQC) and Bluefors, a manufacturer of cryogenic systems, have released a case study detailing SQC’s use of Bluefors’ dilution refrigerators. The collaboration showcases how cryogenic infrastructure enables the company’s research and development in building a commercial quantum computer platform capable of hosting millions of qubits.
SQC’s approach is centered on its 14|15 Platform, which uses individual phosphorus atoms as qubits in a base of isotopically pure silicon-28. The company’s proprietary PAQMan manufacturing process uses Scanning Tunnelling Microscopes (STM) to place these atoms with 0.13 nanometer accuracy. The qubits’ long coherence times and low error rates are attributed to the material simplicity of the platform and the magnetic quiet of silicon-28.
For their research, SQC uses a Bluefors XLD400 System with a Fast Sample Exchange System. This allows the company to test new processors at millikelvin temperatures within a day, which is a foundational element in SQC’s fast-prototyping process and quick chip iteration cycle. The partnership is intended to demonstrate how reliable cryogenic infrastructure plays a role in enabling stable qubit performance and accelerating research.
SQC’s roadmap is to deliver a commercial-scale quantum computer in 2033. The company also designs and manufactures application-specific devices for customers, including “Watermelon” for Quantum Machine Learning (QML) AI-Acceleration and “Quantum Twins” for molecular simulation and surface chemistry.
