Pasqal Integrates Neutral-Atom QPUs Into Multi-Vendor Supercomputing Ecosystems Across Europe and US

[Dan]

Pasqal announced on June 26 that it is integrating its neutral-atom quantum processing units into high-performance computing and supercomputing data centres at multiple vendor sites, moving beyond laboratory deployments into production HPC environments. The integrations span systems including those at Bull-Eviden in France, German supercomputing centres and US national lab partnerships through the Department of Energy's newly established QC-ADDS framework. Pasqal's neutral-atom QPUs operate at room temperature, require no dilution refrigeration and can be reconfigured between different qubit arrangements by repositioning atoms using optical tweezers, offering flexibility that fixed-architecture superconducting systems do not.

The practical integration architecture connects Pasqal QPUs through a hybrid scheduling system that treats quantum processing as a specialised accelerator within the broader HPC workflow. Jobs are submitted to a classical HPC queue, routed to quantum hardware for specific subroutines where quantum advantage applies, and results are returned to the classical compute for post-processing. The scheduling and job management interface uses standard HPC tooling including SLURM extensions, lowering the barrier for HPC users who do not have quantum programming expertise.

OVHcloud running Pasqal's neutral-atom systems alongside Quandela's photonic Belenos system and Quobly's silicon-spin qubit processor on the same cloud platform, all announced within the same week, reflects a multi-modal commercial quantum cloud strategy taking shape in Europe. The different modalities are not competing for the same customers yet: each has different performance profiles for different problem classes. Neutral atoms excel at certain optimisation and simulation tasks. Photonic systems are better suited to certain sampling and machine learning workloads. Silicon spin qubits are targeting long-term scalability. Having all three accessible through one cloud platform is the beginning of quantum-as-a-service at scale.
