NVIDIA’s NVentures Adds Alice & Bob to Its Quantum Portfolio
May 22, 2026 – 8:29 am
The Paris-based cat-qubit company, Alice & Bob, has added NVentures (Nvidia’s venture arm) to its cap table, expanding on its existing backing from FFC, AVP, and Bpifrance. Financial terms of the investment were not disclosed.
Alice & Bob develops fault-tolerant quantum machines using its proprietary cat-qubit architecture. The original Series B funding closed in January 2025, raising €100m (approximately $104.9m at the time), making it one of the larger European quantum hardware rounds on record.
This latest investment by NVentures strengthens Nvidia’s position in the quantum space:
-
Strategic Option & Software Integration: Nvidia is interested in both the strategic option and software integration aspects of Alice & Bob’s cat-qubit hardware, which aligns with its CUDA-Q platform.
-
Hardware-Agnostic Approach: NVentures has invested across various quantum hardware approaches, including Quantinuum (ion trap), QuEra (neutral atoms), PsiQuantum (photonic), and now Alice & Bob (superconducting cat qubits). The goal is to be prepared for whatever architecture reaches fault tolerance first.
-
Fault Tolerance: Alice & Bob claims that its bosonic cat qubits can suppress bit-flip errors at the hardware level, enabling fault tolerance with thousands of physical qubits rather than millions required by other superconducting designs. They aim to deliver a "useful" quantum computer by 2030.
-
State Involvement: The investment comes during a period of increased state involvement in quantum technology, as seen in the US Commerce Department’s CHIPS Act funding and France’s national quantum plan and Proqcima program. Alice & Bob is one of two designated quantum hardware champions under France’s Proqcima initiative.
