The Qatar Investment Authority (QIA) has joined a landmark $1 billion Series E funding round for PsiQuantum, a US-based company aiming to build the world’s first fault-tolerant, million-qubit quantum computers. The investment reinforces Qatar’s growing presence in next-generation technologies and its strategic role in shaping the global innovation landscape.
The fundraising, led by BlackRock with participation from Temasek, Baillie Gifford and other global investors, values PsiQuantum at $7 billion. The round also attracted new backers including Macquarie Capital, Ribbit Capital, NVentures (NVIDIA’s venture arm), Morgan Stanley’s Counterpoint Global, and SentinelOne’s S Ventures.
TL;DR / Key Takeaways
- Qatar Investment Authority (QIA) has invested in PsiQuantum’s $1 billion Series E round, valuing the company at $7 billion.
- PsiQuantum is building million-qubit, fault-tolerant quantum computers using a photonic qubit architecture.
- The company will construct sites in Brisbane and Chicago, expand chip manufacturing, and scale BTO wafer production.
- NVIDIA collaboration announced to integrate GPUs with quantum systems.
- Investment aligns with Qatar National Vision 2030, reinforcing QIA’s role as a global investor in disruptive technologies.
Qatar’s Strategic Bet on the Future of Computing
QIA’s participation underlines Qatar’s strategy of investing in transformative technologies that align with long-term global growth trends. Quantum computing is widely seen as a platform that could reshape industries such as energy, finance, pharmaceuticals, logistics, and climate science.
Industry analysts note that Qatar’s backing of PsiQuantum complements its broader innovation agenda, anchored in Qatar National Vision 2030, by building exposure to disruptive technologies with global impact.
PsiQuantum’s Global Expansion Plans
PsiQuantum will use the new capital to:
- Break ground on utility-scale quantum computing sites in Brisbane, Australia, and Chicago, United States.
- Deploy large-scale prototype systems to validate systems architecture.
- Expand production of its quantum photonic chips.
- Scale up manufacturing of Barium Titanate (BTO) wafers, a key component in ultra-high-performance optical switches.
The company’s approach leverages photonic qubits and high-volume semiconductor manufacturing to overcome challenges of scale, cooling, and networking—barriers that have slowed competitors worldwide.
PsiQuantum also announced a collaboration with NVIDIA, focused on GPU-QPU integration, quantum algorithms, and software development to accelerate progress towards fault-tolerant systems.
A Decade of Progress
Founded nearly a decade ago, PsiQuantum has advanced to mass-manufacturing photonic chips at GlobalFoundries’ semiconductor fabs in the US. Its systems avoid the chandelier-style cryostats used in traditional superconducting qubit designs, instead relying on high-density cooling modules similar to modern data centres.
The company has also demonstrated quantum networking over telecom fibre, a critical step toward connecting multiple quantum processors at scale.
Chief Executive Officer Professor Jeremy O’Brien said:
“Only building the real thing—million-qubit-scale, fault-tolerant machines—will unlock the promise of quantum computing. With this funding, we are ready to take the next decisive steps to deliver its full potential.”
Chief Scientific Officer Dr Pete Shadbolt added:
“We have the chips, the cooling, the networking, the sites, and the support—now we are ready to build utility-scale systems.”
Why It Matters for Qatar
Qatar’s involvement in PsiQuantum’s journey strengthens its global profile as a forward-looking investor committed to technology leadership. By investing in breakthrough computing platforms, QIA is not only diversifying its portfolio but also positioning Qatar as a stakeholder in what could become a trillion-dollar industry.
