Quantonation Ventures, the world’s leading venture firm for quantum and physics-based technologies, has closed its second flagship fund above target at €220 million. With this close, Quantonation becomes the largest dedicated quantum investment firm globally by assets under management.
This second fund is more than twice the size of Quantonation’s first €91 million vintage, which has performed in the top quartile globally, reflecting growing conviction that quantum and deep-physics technologies are moving beyond scientific promise toward industrial systems, enterprise deployment, and real supply chains.
Since launching in 2018, Quantonation has invested globally across more than 10 countries, backing companies in quantum computing, networking, sensing, materials, adjacent supply chain, and broader deep-physics domains. The fund was oversubscribed, surpassing its €200 million target.
All major investors from Quantonation I have returned for the second fund. Returning limited partners include Singapore’s Vertex Holdings; Fonds National d’Amorçage 2, managed by Bpifrance on behalf of the French State; and Bradley M. Bloom, co-founder and former Managing Director of Berkshire Partners. New limited partners include the European Investment Fund, Grupo ACS, Novo Holdings, Planet First Partners, and Toshiba.

“Quantum has spent decades being described as five years away,” said Christophe Jurczak, Managing Partner at Quantonation. “That wasn’t a failure of physics, but of ecosystems. What’s changed is alignment: hardware, software, supply chains, and industrial demand. Quantum is no longer a race to build one machine. It’s an interlocking stack, and that’s where durable value now sits.”
Quantonation backs technologies that take time to scale because progress comes from multiple systems, not a single breakthrough. In physics-based domains, progress is real and compounding, but rarely linear. Hardware, software, materials, supply chains, and policy must mature together, often across different timelines. Quantonation invests early to capture value and impact well before full maturity.
From Quantum Pioneers to Industrial Systems
Quantonation I backed 27 companies worldwide, helping establish quantum technologies as a credible, investable asset class. The portfolio includes category leaders such as PASQAL, Nord Quantique, and Multiverse Computing, alongside a broader body of scientific and engineering progress transitioning from leading laboratories into commercial environments.
“With Quantonation I, our mission was to back the pioneers. These were the teams turning quantum physics into working machines, and to help the first leaders emerge,” said Partner Olivier Tonneau. “With Quantonation II, the focus shifts to utility and scale: demonstrating practical advantage, building robust products, and preparing for industrialisation.”
Quantonation II has already invested in 12 companies and expects to build a portfolio of approximately 25. The larger fund enables Quantonation to write larger initial checks, support companies longer through scale-up, and invest across a broader range of physics-based technologies where progress compounds through engineering and infrastructure rather than speed alone.
“Physics has been a powerful engine for civilizational progress,” said Partner Will Zeng. “Our oversubscribed new fund adds fuel to that engine. We’re backing founders and teams building world-changing companies rooted in better physics and driving the next industrial revolutions.”
