## About

Based in California, US, and founded in 2016 by co-founders Jeremy O'Brien, Terry Rudolph, Pete Shadbolt, and Mark Thompson, PsiQuantum, Corp. operates as a provider of photonic-based quantum computing infrastructure and software platforms to industries such as aerospace, defense, and research institutions, enabling large-scale quantum algorithm development and deployment. In September 2026, PsiQuantum, Corp. received approximately USD 100 million in grant funding from the U.S. Department of Commerce (International Trade Administration).

PsiQuantum develops and deploys quantum computing technologies, notably the Omega quantum photonic chipset, designed for utility-scale applications. This chipset leverages photonic qubits, enabling scalability and rapid production through established semiconductor techniques. PsiQuantum aims to address complex computational challenges across industries like finance, pharmaceuticals, and logistics, collaborating with governmental and private partners in the US, Australia, and other allied nations.

PsiQuantum's revenue model is based on partnerships and agreements with both governmental agencies and private sector clients. Their business-to-business (B2B) revenue structure includes research and development contracts and joint ventures that enable clients to utilize PsiQuantum's quantum computing capabilities. The Omega chipset is central to these agreements, often resulting in multi-year contracts that allow clients early access to advanced technologies, with pricing plans tailored to project scope and strategic value.

The company will use the September 2026 funding for quantum computing operations and quantum computing solution commercialization.
