PRESS RELEASE — Alice & Bob, a leader in fault tolerant quantum computing, announces investment from NVentures, NVIDIA’s venture capital arm, that expands its €100 million Series B round.

The investment supports Alice & Bob’s development of an architecture towards fault-tolerant quantum computing. Financial details of the investment were not disclosed.

“We’ve been working alongside NVIDIA to connect our cat-qubit architecture with its full accelerated computing ecosystem, from hardware to software, in support of the first fault-tolerant quantum computers. 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.” Théau Peronnin, CEO, Alice & Bob

“NVIDIA has built the platform the quantum ecosystem needs to develop and run hybrid quantum-GPU supercomputers, connecting quantum processors to state-of-the-art accelerated computing. Alice & Bob shares NVIDIA’s vision for accelerated quantum supercomputing, and has worked closely with us to integrate their qubits with our quantum platform for advancing the scientific computing of the future,” Timothy Costa, Vice President and General Manager of Quantum at NVIDIA

Alice & Bob and NVIDIA have built close technical collaboration since 2024, including work with NVIDIA CUDA-Q, cuQuantum, and Dynamiqs, Alice & Bob’s open-source quantum simulation library, as well as on NVQLink, NVIDIA’s open architecture for hybrid quantum-classical computing.

Alice & Bob will continue to collaborate with NVIDIA to bring quantum computers to high-performance-computing centers worldwide, integrating cat-qubits with their accelerated computing infrastructure and software stack, as integration projects are ongoing between the two organizations.
