What's happening
On May 22, 2026, NVentures — the venture capital arm of Nvidia (NVDA) — participated in an expansion of Alice & Bob's €100 million Series B financing round, which was originally raised in 2025. The specific dollar amount of NVentures' contribution was not disclosed. Alice & Bob, a French quantum computing company co-founded by CEO Théau Peronnin and Raphael Lescanne, is developing fault-tolerant quantum computing architecture centered on cat qubits, a hardware approach designed to reduce error rates in quantum systems. Other backers in the Series B include Future French Champions (FFC), Atlantic Vantage Point (AVP), and Bpifrance, the French public investment bank.
The NVentures investment deepens an existing technical relationship between the two companies. Alice & Bob has been collaborating with Nvidia on CUDA-Q — Nvidia's open-source platform for hybrid quantum-classical computing — since 2024. CEO Théau Peronnin described the investment as opening a new chapter: "NVentures' investment marks a new phase in that relationship and reinforces our common view that the future of quantum will be hybrid, combining quantum and classical computing to solve real-world problems."
Why it matters for markets
Nvidia currently carries a market capitalization of $5.22 trillion and reported revenue of $253.49 billion, with its dominance built on GPU-accelerated computing and the CUDA software ecosystem. The Alice & Bob investment reflects a pattern of extending that ecosystem into adjacent hardware paradigms before they reach commercial scale. By anchoring Alice & Bob's quantum stack to CUDA-Q, Nvidia positions its software platform as infrastructure for hybrid quantum-classical workloads — a computing model that would require classical GPU acceleration alongside quantum processors, potentially expanding the addressable market for Nvidia's existing data center products.
The €100 million Series B round, backed by a consortium that now includes NVentures alongside Bpifrance and private venture funds, underscores the capital intensity of fault-tolerant quantum hardware development. Cat qubit architectures are considered a longer-horizon technology path compared to near-term noisy intermediate-scale quantum (NISQ) approaches, meaning the commercial timeline for this investment is measured in years rather than quarters. For Nvidia, trading at a P/E of 33.0 against a 52-week range of $132.92 to $236.54, the strategic value of the investment lies less in near-term revenue contribution and more in securing early integration rights within a technology stack that major cloud and enterprise customers are beginning to evaluate seriously.
The French dimension of the deal also carries policy relevance. Bpifrance's participation alongside private investors reflects the French government's sustained commitment to building domestic quantum capability. Nvidia's decision to co-invest alongside a state-backed fund signals confidence in the European quantum supply chain at a time when semiconductor and advanced computing investments are subject to increasing geopolitical scrutiny on both sides of the Atlantic.
Sectors and assets to watch
The primary ticker to monitor is NVDA, where the Alice & Bob investment reinforces the company's strategy of using NVentures to seed technologies that could eventually integrate with its CUDA software ecosystem and data center hardware. Nvidia's CUDA-Q platform, already linked to Alice & Bob since 2024, is the connective tissue between Nvidia's classical GPU infrastructure and emerging quantum processors. Any commercial milestones Alice & Bob achieves in cat qubit fault tolerance could accelerate demand for hybrid quantum-classical computing environments in which Nvidia's H100 and Blackwell GPU architectures would serve as the classical compute layer.
More broadly, the quantum computing sector — which includes publicly traded players developing competing qubit modalities — warrants attention as large-cap technology companies continue to deploy venture capital into the space. Alice & Bob remains privately held, so direct market exposure to this specific development is channeled through Nvidia. Investors tracking the quantum computing theme should note that the €100 million Series B, now expanded with NVentures' participation, represents one of the larger European quantum hardware financing rounds on record, reflecting the capital requirements of scaling fault-tolerant architectures toward practical utility.
What to watch next
Key developments to monitor include any formal announcements regarding the technical scope of the expanded Nvidia-Alice & Bob collaboration on CUDA-Q, particularly whether joint benchmarking results or integration milestones are published. Progress on Alice & Bob's cat qubit roadmap — specifically timelines for demonstrating fault-tolerant logical qubits at scale — will determine how quickly the hybrid computing thesis underpinning this investment can be tested. On the corporate side, observers should watch whether NVentures makes additional investments in quantum hardware firms, which would indicate whether this is an isolated strategic bet or the beginning of a broader quantum portfolio strategy within Nvidia's venture arm.
