PsiQuantum secured $1 billion in Series E funding. Funds and accounts managed by affiliates of BlackRock led the round. Temasek and Baillie Gifford also served as lead investors. This capital will accelerate the development of fault-tolerant quantum computers.
The funding values PsiQuantum at $7 billion. It enables the company to establish utility-scale quantum computing sites. These locations include Brisbane and Chicago. Furthermore, PsiQuantum will deploy large-scale prototype systems.
Advancing Quantum Technology and Partnerships
PsiQuantum focuses on photonic qubits for error correction. This approach leverages high-volume semiconductor manufacturing. The company collaborates with NVIDIA on quantum algorithms and GPU-QPU integration. Their Omega chipset, manufactured at GlobalFoundries’ Fab 8, utilizes Barium Titanate (BTO).
BTO integration enables ultra-high-performance optical switches. PsiQuantum manufactures 300mm BTO wafers in California. This technology also holds potential for next-generation AI supercomputers. Moreover, the company developed a high-density cooling solution, unlike traditional cryostats.
PsiQuantum demonstrated high-fidelity quantum networking using standard telecom fiber. This capability is crucial for utility-scale quantum computing. The company aims to deliver commercially useful machines, differentiating its approach from IBM Quantum or Google Quantum AI.
