Nvidia invests in Alice & Bob quantum computing startup
Nvidia’s venture capital arm NVentures has invested in Paris-based quantum computing company Alice & Bob, extending the firm’s Series B funding round to 100 million euros. The company confirmed the deal on Friday, while financial terms of the transaction were not disclosed. The new capital brings Alice & Bob’s total funding to approximately 230 million euros since its creation in 2020.
The Series B extension adds NVentures to an existing investor base that includes Future French Champions, AXA Venture Partners, and Bpifrance, which led the initial round closed in January 2025. Founded in Paris, Alice & Bob has positioned itself as one of France’s leading quantum hardware developers and a key beneficiary of national strategic funding for advanced computing technologies.
Nvidia’s investment reflects a broader strategy focused on quantum computing infrastructure rather than direct competition in hardware development. The company is building an ecosystem that connects classical high-performance computing with emerging quantum systems. Through NVentures, Nvidia has already backed several competing quantum approaches, including trapped-ion systems, neutral atoms, and photonic architectures, before adding Alice & Bob’s superconducting “cat qubit” model to its portfolio.
The French startup’s technology is integrated into Nvidia’s CUDA-Q platform and its NVQLink interconnect system, which links classical accelerators with quantum processors. Alice & Bob’s approach uses bosonic cat qubits designed to suppress bit-flip errors at the hardware level. The company argues this could reduce the number of physical qubits required for fault-tolerant quantum computing, potentially shifting the scale from millions of qubits to far fewer high-quality logical units.
The investment arrives amid a surge in public and private funding for quantum technologies. The United States has committed multi-billion-dollar support through semiconductor and advanced computing programs, while France has allocated 1.8 billion euros under its national quantum strategy launched in 2021. Alice & Bob is among the designated national champions in quantum hardware development under this initiative.
The company aims to build a useful quantum computer by 2030, targeting 100 high-fidelity logical qubits. It also plans to nearly double its workforce, adding around 100 employees by mid-2026 to accelerate both research and commercial development.
