Quantonation Ventures Closes €220 Million Fund to Propel Deep Tech Innovation
Paris, Monday 23 February 2026
Quantonation Ventures has successfully closed its second early-stage fund at €220 million as of 18 February 2026, significantly exceeding its initial target and doubling the size of its 2021 vintage. This substantial capital injection defies market scepticism regarding a potential ‘quantum winter’, signaling profound investor confidence in the European deep tech ecosystem. Backed by institutional heavyweights such as the European Investment Fund and Bpifrance, the fund targets physics-based startups, having already invested in 12 ventures including Pasqal and Quandela. This development underscores a pivotal moment for the sector, aligning with recent industry assessments that quantum computing is reaching a critical inflection point for commercial viability.
Scaling Up Amidst Market Shifts
The closing of this second vintage on 18 February 2026 represents a substantial escalation in capital commitment compared to the firm’s inaugural fund, which closed at €91 million in 2021 [1][2]. This increase of 141.758 per cent in fund size highlights the growing maturity of the deep tech sector, bringing the total capital raised by the firm since its inception in 2018 to approximately €325 million [4]. The fund exceeded its initial target of €200 million, a feat that defies the narrative of a ‘quantum winter’ and suggests that specialised investors remain bullish on the long-term prospects of physics-based innovation [4][1].
Strategic Deployment in a Maturing Market
Capital deployment is already underway, with the firm having invested in 12 startups and aiming for a total portfolio of approximately 25 companies [1]. While Quantonation maintains a strong foothold in France through investments in champions like Pasqal and Quandela, its strategy is explicitly global, targeting ventures across North America and Asia [1]. The investment scope is also widening; beyond core computing hardware, the fund is targeting software, industrial layers, photonics, and lasers [1]. This diversification reflects a shift in the types of investment opportunities available, as noted by partner Will Zeng, who observes that research in these fields is emerging from universities globally rather than a single hub [1].
An Inflection Point for Hardware
The timing of this fund closure aligns with significant technical and industrial milestones. Olivier Tonneau, founder and partner at Quantonation, stated on 18 February 2026 that the new funds are specifically earmarked to industrialise quantum technology [3]. This follows a period of technical validation, including Google’s 2024 ‘Willow’ chip landmark for error correction and the assessment by Nvidia CEO Jensen Huang in June 2025 that quantum computing is reaching an “inflection point” [1]. These developments suggest the sector is moving from theoretical research toward tangible commercial utility.
Global Backing for a Distributed Future
The fund’s oversubscription was driven by a diverse coalition of global investors, including Singapore’s Vertex Holdings, the European Investment Fund, Bpifrance, Grupo ACS, Novo Holdings, Planet First Partners, and Toshiba [1]. Operating with dual headquarters in Paris and New York City, the firm is positioned to capture value in a market where no clear regional winner has yet emerged [1]. This robust activity in deep tech coincides with a broader resurgence in the European market; as of 20 February 2026, global investors were allocating record amounts to European equities, driven by optimism regarding the region’s economic health [2].
