. The partnership centers on enhancing Qaptiva, software developed by state-owned supercomputer maker Bull, to provide an alternative to Nvidia's CUDA-Q platform. CEA, a research center with an annual budget of nearly €6 billion that oversees France's nuclear deterrent, will become an early customer for French startups while granting them access to its computing facilities to boost the domestic quantum industry1

Addressing the Software Bottleneck in AI

Executives at both CEA Alice & Bob emphasized their goal to prevent the software bottleneck that exists around CUDA in AI from replicating in quantum computing2

. The collaboration seeks to develop software for linking quantum processors with traditional supercomputers, assigning quantum machines only the portions of problems where they may eventually offer computational advantages. Alice & Bob stated that quantum software is the component that makes the technology usable, noting that more alternatives accelerate progress across the entire field2

. This strategic approach aims to ensure the quantum computing ecosystem remains open and competitive rather than dominated by a single vendor's software platform.

Building France's Quantum Infrastructure

CEA has already installed quantum computers from French companies Quandela and Pasqal alongside its classical supercomputer infrastructure1

. The commission plans to add Alice & Bob's quantum processor in 2027, creating a comprehensive testbed for integrating quantum computers with supercomputers. The initial focus will explore applications in materials physics, demonstrating practical use cases for hybrid quantum-classical computing architectures1

. This infrastructure investment positions France to compete globally in quantum technology development while supporting its domestic quantum industry through early adoption and facility access. The partnership represents a deliberate effort to establish European alternatives in quantum software before market consolidation creates dependencies similar to those seen in AI workloads, where Nvidia's CUDA platform has become nearly ubiquitous.
