The Qatar Investment Authority (QIA) joined a USD 1 billion Series E funding round for California-based quantum computing company PsiQuantum, the sovereign wealth fund announced on September 10, 2025. The round was led by affiliates of BlackRock, along with Temasek and Baillie Gifford, and valued PsiQuantum at USD 7 billion.
According to QIA’s statement, the funding will equip PsiQuantum to break ground on utility-scale quantum computing sites in Brisbane, Australia, and Chicago, deploy large-scale prototype systems, and advance its quantum photonic chip technology. QIA did not disclose the exact size of its investment.
A QIA spokesperson described the investment as evidence of the fund’s vision for “the transformative possibilities of quantum technologies” and its commitment to establishing international partnerships in future-shaping sectors. The PsiQuantum investment was QIA’s second publicly disclosed quantum computing deal in 2025, following its co-leadership of a EUR 100 million round for French startup Alice and Bob in January.
