Bull and quantum hardware developer Alice & Bob have signed a Memorandum of Understanding to integrate quantum computing systems within high-performance computing (HPC) infrastructures. The initiative aims to connect quantum architectures with computing infrastructures to operate as co-processors. By combining Bull’s system integration and manufacturing capabilities with Alice & Bob’s superconducting qubit technology, the collaboration addresses the physical and structural requirements for large-scale quantum (LSQ) hybrid acceleration.
At the core of the technical alliance is Alice & Bob’s cat qubit architecture, a superconducting qubit design engineered to suppress bit-flip errors. By managing bit-flips at the hardware level via autonomous quantum stabilization, this approach alters the physical resource requirements typically demanded by quantum error correction (QEC) frameworks. Performance data indicates that the cat qubit architecture reduces the total number of physical qubits required to build an error-corrected machine by up to 200 times compared to standard alternative approaches, changing the structural footprint and cooling loads needed to scale up to large-scale quantum computers.
The software track focuses on expanding Bull’s hardware-agnostic Qaptiva platform to support error-corrected hardware operations. Under the direction of Bull Head of HPC, AI, and Quantum Computing Bruno Lecointe and Alice & Bob COO Chloé Poisbeau, the partnership will extend the functional capacities of the Qaptiva HPC and Qaptiva Access software environments to enable cat qubit emulation and hybrid execution on physical chips. Utilizing Bull’s manufacturing facility in Angers, France, the companies plan to deploy secure, on-premises hybrid hardware installations across France, the UK, and Germany to align with national computing infrastructure programs.
