NVIDIA, the global leader in GPUs and AI computing, is reportedly in advanced discussions to invest in PsiQuantum, a California-based quantum computing startup pioneering a new class of photonic quantum computers. This move, if finalized, would mark a significant step by NVIDIA into the next frontier of computation—quantum computing—further cementing its position as a technological trailblazer.
Founded in 2016 by physicists Jeremy O’Brien, Terry Rudolph, and others, PsiQuantum is developing fault-tolerant quantum computers using photons—particles of light—as qubits. Unlike traditional qubit systems that rely on superconducting circuits (like Google or IBM) or trapped ions (like IonQ), PsiQuantum’s silicon photonics approach is aimed at leveraging existing semiconductor manufacturing infrastructure to scale quantum computing reliably.
The company’s ultimate goal is to build a 1 million-qubit quantum computer capable of solving problems in chemistry, cryptography, drug discovery, and climate modeling—tasks infeasible for classical supercomputers. PsiQuantum’s progress has already attracted over $665 million in funding from investors such as BlackRock, Temasek, and Microsoft’s M12, placing it among the most well-funded startups in the quantum space.
NVIDIA’s interest in quantum computing isn’t new. While the company has dominated AI and HPC (high-performance computing) through its GPUs like the H100 and Blackwell B200, it recognizes that classical computing—even at exascale—has limitations. As AI model complexity and simulation demands grow, quantum computing is seen as the natural extension for problems where exponential scaling of compute is required.
An investment in PsiQuantum could enable NVIDIA to:
● Integrate photonic quantum computing with its existing data center and AI infrastructure.
● Develop hybrid classical-quantum systems leveraging NVIDIA’s GPUs alongside PsiQuantum’s quantum processors.
● Position itself early in the quantum ecosystem—possibly building a "CUDA for quantum" platform in the future.
This potential deal reflects a larger industry trend where tech giants hedge their future by backing quantum startups. Amazon, Microsoft, IBM, and Google already have active quantum divisions or investments. NVIDIA’s partnership with PsiQuantum would distinguish itself by focusing on photonic qubits, a less-explored but highly scalable technology.
Additionally, this aligns with NVIDIA’s broader platform strategy—extending its ecosystem of AI, networking (Mellanox), CPUs (Grace), and data centers (DGX Cloud) into quantum acceleration, providing end-to-end solutions for enterprises and scientific institutions.
Industry analysts view the potential investment as a logical and strategic leap. According to IDTechEx and McKinsey, the quantum computing market could reach $90 billion by 2040, and early access to proprietary quantum IP will be a massive competitive advantage.
Dr. O’Brien, CEO of PsiQuantum, has previously emphasized the importance of industry collaboration to make quantum a practical reality: “You don’t build a million-qubit system in a garage. It requires deep ecosystem partnerships and the infrastructure of modern chip fabs.”
While the deal is still under negotiation, its announcement could signal a paradigm shift in how classical computing leaders engage with quantum technology. If successful, NVIDIA would not only gain strategic visibility into the quantum hardware roadmap but also reshape its own future in computing.
