Scaleway has announced the integration of its Quantum-as-a-Service platform with NVIDIA's CUDA-Q runtime, allowing developers to execute quantum workloads on GPU clusters or real quantum processors through a unified interface without changing tools or managing separate environments. The integration provides access to state vector emulation scaling up to 38 qubits across eight interconnected NVIDIA Blackwell Ultra GPUs, as well as access to superconducting quantum processors from IQM Quantum Computers and trapped-ion systems from Alpine Quantum Technologies.

Why it matters

This integration establishes Scaleway as Europe's leading multi-modal quantum cloud aggregator, combining large-scale GPU emulation and access to production-grade quantum hardware under a single platform. It removes the traditional barrier between quantum experimentation and real-world validation, allowing developers to seamlessly move ideas from simulation to hardware in a single workflow.

The details

With the CUDA-Q integration, developers can write their quantum programs once and choose where to run them - on NVIDIA Hopper and Blackwell GPU architectures operated by Scaleway, or on real quantum processors through Scaleway's quantum hardware partners. This eliminates the need for infrastructure orchestration, provisioning GPU clusters, or negotiating separate access to quantum hardware providers.

  • Scaleway announced the integration on March 18, 2026 at the NVIDIA GTC conference in San Jose, California.

What they’re saying

“What we find particularly exciting about CUDA-Q is its multi-paradigm approach. It brings classical HPC techniques and quantum development into the same workflow, which feels like the right direction for the ecosystem. We're looking forward not only to building on top of CUDA-Q, but also to contributing to it. Combining NVIDIA's HPC expertise with our cloud-native GPU infrastructure allows us to push emulation performance to the next level while keeping things simple for developers.”

— Valentin Macheret, Engineering Manager at Scaleway

“Access to large scale simulations and state of the art quantum hardware are allowing researchers to explore and develop for future hybrid quantum-classical supercomputers. Scaleway's integration of CUDA-Q is allowing them to offer quantum developers the GPU-accelerated tools and interface to physical QPUs, accelerating how they test and scale their work.”

— Sam Stanwyck, Director of Quantum Product at NVIDIA

What’s next

Scaleway plans to continue expanding its Quantum-as-a-Service platform by adding support for more quantum hardware providers and enhancing the capabilities of its GPU-accelerated emulation environment.

The takeaway

Scaleway's integration of NVIDIA's CUDA-Q runtime into its Quantum-as-a-Service platform represents a significant step forward in making quantum computing more accessible and usable for developers, researchers, and enterprises. By combining large-scale GPU emulation and access to real quantum hardware under a single cloud-based interface, Scaleway is positioning itself as a leading provider of hybrid quantum-classical computing solutions in Europe.
