Bull and Alice & Bob Sign MoU to Integrate Cat-Qubit Quantum Computers into HPC Environments

Advanced computing and AI provider, Bull, and Alice & Bob, a leader in fault-tolerant quantum computing specialising in cat qubits, today, June 24, 2026, announced the signing of a Memorandum of Understanding (MoU). The agreement extends their joint collaboration across research, product innovation, and commercialisation, with the objective of bringing quantum computing capabilities into high-performance computing (HPC) environments.

Integrating Cat Qubits into HPC Workflows

Alice & Bob develops quantum processors based on cat qubits, a bosonic encoding approach in superconducting circuits that provides inherent protection against bit-flip errors. This design significantly reduces the overhead required for quantum error correction compared with standard transmon-based approaches. Under the MoU, the companies will focus on technical integration pathways that allow these quantum processing units to operate as schedulable resources alongside classical processors in Bull’s HPC environments.

Effective hybrid operation requires advances in low-latency control interfaces, job scheduling extensions (such as SLURM compatibility), and software layers that manage data movement and orchestration between classical and quantum domains. By addressing these integration challenges, the collaboration aims to make early fault-tolerant quantum resources more accessible within existing European supercomputing infrastructures, supporting both research exploration and the development of practical hybrid algorithms.

Accelerating Commercial Quantum-HPC Solutions in Europe

Bull supplies established supercomputing systems, IT infrastructure, and quantum emulation tools widely used by research institutions and industry across Europe. By aligning these capabilities with Alice & Bob’s roadmap for fault-tolerant quantum computers, the partnership seeks to lower the technical and operational barriers that currently limit broader adoption of quantum acceleration.

The MoU emphasizes joint work on product innovation and commercialization pathways. This includes developing integrated offerings that combine Bull’s HPC platforms with Alice & Bob’s cat-qubit systems, enabling organizations to run hybrid quantum-classical computing workloads without requiring entirely new infrastructure or specialized expertise. Such integrated solutions are increasingly viewed as essential for scaling quantum utility in domains such as materials simulation, optimization, and scientific discovery.

For European stakeholders, the collaboration supports strategic objectives around technological sovereignty and the creation of a robust domestic quantum ecosystem. By focusing on practical integration and commercial readiness, Bull and Alice & Bob aim to accelerate the transition from experimental quantum systems to production-ready hybrid computing capabilities that can deliver measurable advantage alongside existing classical HPC investments.
