Alice & Bob develops a cat‑qubit architecture aimed at achieving fault‑tolerant quantum computing and building hybrid quantum–GPU systems. The company has worked closely with NVIDIA since 2024 to integrate its qubits with NVIDIA’s accelerated computing stack, including CUDA‑Q, cuQuantum and NVQLink, and maintains an open‑source quantum simulation library called Dynamiqs. Its stated plans include integrating cat‑qubits with high‑performance computing centres worldwide to advance hybrid quantum‑classical supercomputing. Financially, Alice & Bob’s Series B was sized at €100 million and the round was expanded with an investment from NVentures, though specific terms of that investment were not disclosed. Ongoing integration projects with NVIDIA form a key part of its technical and commercialization roadmap.
