Scaleway QaaS Achieves Full NVIDIA CUDA-Q Compatibility for Hybrid Quantum Development

Scaleway has announced full compatibility between its Quantum-as-a-Service (QaaS) platform and the NVIDIA CUDA-Q runtime, allowing developers to execute quantum kernels across a hybrid infrastructure. Through this integration, users can write a single codebase in CUDA-Q and switch between high-performance GPU clusters and physical quantum hardware without modifying their development environment. This unified interface removes the need for manual infrastructure orchestration, such as provisioning GPU clusters or managing individual access to multiple hardware providers, positioning Scaleway as a central European aggregator for multi-modal quantum cloud services.

The platform provides an on-demand state-vector emulation environment capable of simulating up to 38 noiseless qubits. This is achieved by leveraging a cluster of eight interconnected NVIDIA Blackwell Ultra GPUs via NVIDIA NVLink, which overcomes the traditional memory wall encountered by conventional systems at approximately 30 qubits. For hardware execution, the service provides access to various European quantum modalities, including superconducting transmon systems from IQM Quantum Computers (Garnet, Sirius, and Emerald models) and the IBEX Q1 trapped-ion processor from Alpine Quantum Technologies (AQT).

By integrating CUDA-Q natively within a European sovereign cloud framework, Scaleway addresses data residency and digital sovereignty requirements for organizations in the region. The workflow enables researchers and enterprises to transition from large-scale simulation on NVIDIA Hopper and Blackwell architectures to real-world validation on physical QPUs in a single, streamlined process. This hybrid approach is intended to accelerate the development of next-generation applications in AI and scientific research by combining classical HPC techniques with diverse quantum hardware modalities under a single cloud-native interface.
