Quantonation Ventures has finalized its second fund at €220 million ($260 million), more than doubling the €91 million raised for its debut fund in 2018. This Paris- and New York-based firm, a leader in quantum and deep physics investments, achieved this first close ahead of its €200 million target, positioning it as the world’s largest dedicated quantum venture fund. The milestone reflects sustained investor confidence amid a maturing quantum ecosystem, with global funding reaching $5 billion last year despite lingering skepticism about commercialization timelines.
Fund Growth Signals Quantum’s Staying Power
Quantonation’s first fund delivered top-quartile returns, fueling demand for this larger successor. The new capital will support around 25 early-stage companies, with check sizes expanded to drive scaling from prototypes to industrial applications. Already, 12 investments are in place, targeting not just quantum processors but also enabling technologies like sensors, error-correction software, photonics, and advanced materials. This broad “deep physics” strategy addresses the full stack needed for practical quantum systems, from hardware to integration tools.
Backers now expect quicker paths to revenue as quantum tackles real problems. While full fault-tolerant computing may take years, hybrid systems blending quantum and classical tech offer early wins in optimization and simulation. Quantonation’s team, including PhD physicists Christophe Jurczak and Will Zeng, plus Nobel laureate Alain Aspect as advisor, leverages deep expertise to spot winners early. Their track record includes exits and growth stories that validate the approach.
Timeline of Commitments and Key Backers
The fund’s buildup began in April 2024 with a €70 million first close. Momentum built through 2025, highlighted by the European Investment Fund’s (EIF) €30 million commitment in June under the InvestEU program. “This investment strengthens Europe’s ambition to lead in next-generation technologies,” said EIF’s Marjut Falkstedt at the time. Additional limited partners include returning investors Bpifrance and Planet First Partners, alongside newcomers like Singapore’s Vertex Holdings, Novo Holdings, and Toshiba.
Novo Holdings, the investment arm of Denmark’s Novo Nordisk Foundation, enters quantum to support biotech simulations for drug discovery—quantum could slash years off molecule modeling. Toshiba, a pioneer in superconducting qubits, seeks ecosystem plays to bolster its hardware roadmap. These corporate moves highlight strategic bets on quantum’s role in core businesses, blending financial returns with tech synergies.
Portfolio Focus: Tackling Core Quantum Challenges
Quantonation prioritizes areas critical to industrialization. Error correction remains a major hurdle: quantum bits (qubits) are fragile, prone to decoherence that corrupts computations after mere microseconds. Investments target scalable fixes, such as software algorithms and hardware stabilizers that could push coherence times to minutes. Communications and sensing applications, less demanding than full-scale computing, offer nearer-term revenue through secure networks and precision imaging.
Early portfolio companies exemplify this. Diraq develops silicon spin qubits, leveraging mature semiconductor fabs for affordable, scalable quantum chips—potentially millions of qubits on standard lines, slashing costs from cryogenic rarities. SteerLight’s photonics-based LiDAR uses quantum-inspired optics for automotive sensing, achieving longer range and better resolution in fog or darkness, ideal for self-driving cars. Resolve Stroke advances quantum-enhanced MRI for faster, clearer brain scans, aiding emergency diagnostics where seconds count.
PioniQ focuses on energy storage materials, using quantum chemistry simulations to design solid-state batteries with higher density and faster charging—key for EVs and grid stability, where current lithium limits scale. From the first fund, standouts include Pasqal’s neutral-atom processors for hybrid quantum-classical workloads in finance, Quandela’s photonic qubits for networked quantum systems, and Quobly’s topological qubits promising inherent error resistance via anyon particles. Others like Welinq (quantum repeaters for internet-scale links), QphoX (cryogenic interfaces), and software firms Multiverse Computing and Kipu Quantum round out a portfolio blending hardware, software, and applications. These firms have raised follow-on rounds, validating Quantonation’s seed-stage bets.
Expert Perspectives on the Path Forward
“Physics is the engine of disruption, and this fund provides the fuel for founders pioneering the next industrial revolution,” said Partner Will Zeng. Jurczak echoed this, emphasizing the need to “industrialize quantum technologies” amid global competition. Falkstedt from the EIF highlighted Europe’s edge, backed by public-private synergy. Investor interest points to building robust supply chains, from specialized fabs to accessible quantum clouds.
Market dynamics support optimism. Quantum funding hit records in 2025, driven by U.S. and Chinese advances, but Europe gains via policy like the EU Quantum Flagship. Challenges persist—error rates above the 0.1% limit algorithms, and cryogenic cooling adds costs—but targeted investments like Quantonation’s aim to halve error thresholds within years. Photonics and sensing could yield $10 billion markets by 2030, per analyst forecasts.
Implications for the Quantum Ecosystem
This fund arrives as quantum transitions from research to revenue. Big Tech like IBM and Google offer cloud access, but specialized VC fills the gap for risky deep-tech bets. Quantonation’s global mandate—Europe, U.S., Asia-Pacific—ensures exposure to innovations like Japan’s superconducting advances or Australia’s silicon efforts. With 13 slots left, expect announcements in error-corrected logical qubits and hybrid systems.
For startups, larger tickets mean sustained runway through Series A/B, reducing dilution and failure risks in a capital-intensive field. Investors gain diversified access to a sector projected to unlock $1 trillion in value by 2040, from drug discovery to optimization. Quantonation’s achievement counters doubts about investment sustainability. Quantum supply chains are taking shape, with this fund accelerating the shift to deployable technologies.
