PsiQuantum is emerging as a major quantum computing startup with a focus on photonic-based systems for scalable solutions.
Nvidia is reportedly in advanced talks to invest in PsiQuantum, signaling growing convergence between AI and quantum computing.
Massive funding and global projects position PsiQuantum as a key contender in the race for utility-scale quantum computing.
PsiQuantum, a Silicon Valley-based quantum computing startup, is rapidly emerging as a pivotal player in the next wave of artificial intelligence (AI) and high-performance computing. With a focus on developing utility-scale, fault-tolerant quantum computers, the company has garnered significant attention from major investors and government entities alike.
PsiQuantum is in advanced discussions with Nvidia as of May, 2025 for a strategic investment, signaling a potential shift in the quantum computing landscape.
Founded in 2016 by Jeremy O'Brien, Terry Rudolph, Peter Shadbolt, and Mark Thompson, PsiQuantum is headquartered in Palo Alto, California. The company's mission is to build the world's first useful quantum computer using a photonic approach, leveraging existing semiconductor manufacturing techniques. This strategy aims to facilitate scalability and integration with current technological infrastructures.
In May 2025, reports emerged that Nvidia is in advanced talks to invest in PsiQuantum. This move aligns with Nvidia's broader strategy to expand into quantum computing, complementing its existing AI and high-performance computing portfolio. The potential investment underscores the growing convergence between quantum computing and AI, with companies seeking to harness quantum capabilities to solve complex problems beyond the reach of classical computers.
PsiQuantum has raised significant capital to advance its ambitious goals. In March 2025, the company secured at least $750 million in funding, led by BlackRock, at a pre-money valuation of $6 billion. Previous funding rounds have included investments from Microsoft's venture fund M12, Baillie Gifford, and Temasek. These substantial investments reflect confidence in PsiQuantum's approach and its potential to revolutionize computing.
PsiQuantum is actively engaged in constructing two major quantum computing facilities: one in Brisbane, Australia, and another in Chicago, Illinois. The Brisbane project, supported by nearly $1 billion in combined funding from the Australian federal and Queensland governments, aims to establish a 1-million-qubit quantum computer. This initiative positions Brisbane as a potential global hub for quantum computing and research.
In Chicago, PsiQuantum is collaborating with local and state authorities to develop the Illinois Quantum and Microelectronics Park. This facility is part of a broader effort to transform the region into a center for quantum innovation, leveraging existing research institutions and infrastructure.
PsiQuantum's strategy centers on using photonic qubits, which involve encoding information in particles of light. This method offers advantages in terms of error correction and scalability, as it can utilize existing semiconductor fabrication processes. By partnering with GlobalFoundries, PsiQuantum aims to produce quantum chips at scale, accelerating the development and deployment of quantum computing systems.
While PsiQuantum remains a private company, its activities are closely watched by investors and industry analysts. The company's focus on building a fault-tolerant, utility-scale quantum computer positions it as a potential leader in the field. However, challenges remain, including technological hurdles and the need for continued funding.
The potential investment from Nvidia could provide not only capital but also strategic alignment, integrating PsiQuantum's quantum capabilities with Nvidia's AI and computing platforms. Such a partnership could accelerate the commercialization of quantum computing applications across various industries, including pharmaceuticals, finance, and materials science.
PsiQuantum's ambitious projects and strategic collaborations underscore its commitment to advancing quantum computing. The company's photonic approach, combined with significant investments and government support, positions it as a formidable contender in the race to achieve practical quantum computing. As developments unfold, PsiQuantum's progress will be a key indicator of the trajectory of quantum technology integration into mainstream computing.
