Paris, France – 24 June, 2026 – Bull, a leader in advanced computing and AI, and Alice & Bob, a leader in fault-tolerant quantum computing specialising in cat qubits, today announce the signature of a Memorandum of Understanding to extend their joint collaboration across research, product innovation and commercialisation. Together, Bull and Alice & Bob now aim to deepen their collaboration to accelerate the development and adoption of quantum technologies in Europe and beyond. From experimentation to broader industrial collaboration Under this agreement, the two companies will expand their cooperation in four key areas: - Research & development – advancing quantum applications, particularly in material physics, and strengthening the integration of large-scale quantum1 (LSQ) systems within high-performance computing environments - Product innovation – exploring new offerings, including the containerisation and the assembly of quantum systems. - Software development – extending the capability of Bull’s software tools, including Qaptiva HPC and Qaptiva Access, to better support emulation of cat qubits as well as enable execution on Alice & Bob’s cat qubit chips in a HPC environment - Commercial development – jointly addressing new business opportunities worldwide, with a focus on sovereignty-driven projects. Combining complementary strengths These efforts reflect a shared ambition to move beyond early-stage experimentation, bridging the gap between quantum hardware innovation and its practical, scalable use in real-world environments as the industry enters its next phase. Alice & Bob and Bull bring highly complementary strengths to this ambition. Alice & Bob is focused on building a universal, fault-tolerant quantum computer, with its cat qubit technology designed to significantly reduce the hardware requirements for large-scale systems. This approach is combined with Bull’s long-standing expertise in high-performance computing, system integration and global support, as well as its industrial capabilities, including its manufacturing site in Angers and strong international footprint.
