NVentures, the venture capital arm of NVIDIA, has invested in Alice & Bob's Series B extension, bolstering the company's development of fault-tolerant quantum computing architecture utilizing cat qubits. This investment expands Alice & Bob's initial €100 million Series B round. The collaboration between Alice & Bob and NVIDIA, which began in 2024, focuses on integrating the former's technology with the latter's hybrid quantum-classical computing ecosystem, including CUDA-Q and cuQuantum. The partnership aims to bring hybrid quantum-GPU systems to high-performance computing centers, leveraging NVQLink and Dynamiqs. This development has significant implications for the cryptographic landscape, as NVIDIA's advancements in quantum computing accelerate the need for post-quantum cryptography migration1. So what matters to practitioners is that this investment underscores the urgency of planning for post-quantum cryptography, as the timeline for migration narrows.
