Silicon Quantum Computing

Silicon Quantum Computing (SQC) is Australia's first quantum computing company that builds commercial-scale quantum computers. They use the (relatively unproven) silicon-based approach to building quantum computers, which the company claims have the lowest electrical noise (creating a higher quality of qubits).

In June 2022, the company developed the world’s first integrated quantum computer circuit , including all components of a classical computer, with quantum-scaled transistors (the size of a single atom).

Key customers and partnerships

In August 2023, SQC and the University of New South Wales Sydney extended the existing R&D collaboration with Silex (initially entered in December 2019) to lead the production of high-purity “Zero-Spin Silicon” to advance quantum computing processes.

Funding and financials

SQC was launched in May 2017 with over AUD 83 million of capital funding from the Australian Government, the University of New South Wales, and several private investors. In July 2023, the company raised AUD 50.4 million (USD 34 million) in Series A funding round with participation from the Commonwealth Bank, University of New South Wales, Telstra, and the Australian Government. The proceeds were earmarked to accelerate the company’s hardware development plans, including introducing a 10-qubit prototype processor by 2023 and building a 100-qubit quantum device by 2028.
