Nvidia is investing, through its NVentures arm, in the French deeptech Alice & Bob.
The move strengthens a €100 million Series B announced in early 2025 and confirms the GPU giant’s growing interest in technologies capable of bringing quantum computing closer to industrial use. The investment amount remains undisclosed, but it fits within a long-standing relationship between the two companies.
Since 2024, Alice & Bob and Nvidia have collaborated on several technical building blocks, including CUDA-Q, cuQuantum, Dynamiqs, and NVQLink, with the goal of linking quantum processors to accelerated computing infrastructures.
Alice & Bob stands out for its fault-tolerant quantum approach, built on cat qubits. This architecture aims to reduce computational errors, one of the main obstacles to constructing truly scalable quantum computers that are practically usable.
A Bet on Cat Qubits
For Nvidia, the interest goes beyond sheer financial logic. The group aims to build a hybrid ecosystem where GPUs, simulation software, and quantum hardware work more closely together, in order to accelerate the development of machines that are more robust and more useful for industry.
Based in Paris and Boston, Alice & Bob counts more than 230 employees and is developing a production, research and development center of 4,000 square meters north of Paris. The company aims to deliver a quantum computer useful to industry by 2030.
This new equity entry comes as the global quantum race intensifies, with American, European and Asian players scaling up investments in the most promising architectures. In this context, Nvidia’s backing provides Alice & Bob with greater visibility among major industrial players and computing centers.
For Nvidia, the investment is part of a broader strategy to position itself at the heart of the future quantum value chain, by combining computing power, software, and interconnection with quantum processors.
It is also a market signal: the group no longer merely observes quantum computing, it is gradually establishing a presence in it.
