Insider Brief
- Scaleway has announced full compatibility of its Quantum as a Service platform with NVIDIA CUDA-Q runtime, enabling developers to execute 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 via NVLink, along with access to superconducting quantum processors from IQM Quantum Computers and trapped-ion systems from Alpine Quantum Technologies.
- Developers can write CUDA-Q kernels once and seamlessly switch between large-scale GPU emulation on NVIDIA Hopper and Blackwell architectures and production-grade quantum processors by selecting different execution backends within Scaleway’s cloud platform.
PRESS RELEASE — On the occasion of NVIDIA GTC in San Jose, Scaleway announces full compatibility of its Quantum as a Service platform with the NVIDIA CUDA-Q runtime.
Developers can now write CUDA-Q kernels, select Scaleway as their preferred backend, and execute workloads seamlessly either on high performance GPU clusters or on real quantum processors without changing tools or managing separate environments.
This integration gives users direct access to Scaleway from within CUDA-Q, enabling ultrahigh performance state vector emulation on dedicated hardware, with no mutualized queueing, and unified access to multiple European quantum hardware modalities through a single cloud interface.
From Development to Execution in a Single Workflow
With CUDA-Q integration, the development process becomes straightforward. Teams write their quantum programs once and choose where to run them.
They can execute large scale simulations on NVIDIA Hopper and NVIDIA Blackwell architectures operated by Scaleway, or run the same code on real quantum processors through Scaleway’s quantum partners, simply by selecting a different execution machine.
No infrastructure orchestration is required on the user side. There is no need to provision GPU clusters, manage schedulers, or negotiate separate access to quantum hardware providers.
In practice, CUDA-Q becomes a direct gateway to supercomputing scale infrastructure delivered as a cloud service.
Powerful on demand state vector emulation platform
With this release, Scaleway becomes the most convenient and powerful on demand state vector emulation platform worldwide.
Running across eight interconnected NVIDIA Blackwell Ultra GPUs via NVIDIA NVLink, simulations can scale up to 38 qubits in full state vector representation. This removes the typical local memory wall encountered around thirty qubits on conventional systems and significantly exceeds the limits of many other open source emulators.
Large scale emulation becomes accessible instantly, without capital expenditure or investment in specialized hardware. Researchers, startups, and enterprises can experiment at supercomputing scale on demand.
A unified bridge between emulated and real quantum hardware
Beyond emulation, Scaleway provides access to real gate based quantum processors within the same environment.
Through Scaleway’s Quantum as a Service, developers can execute workloads on superconducting transmons systems from IQM Quantum Computers, including Garnet (20 qubits), Sirius (16 qubits), and Emerald (54 qubits), as well as on the trapped ion IBEX Q1 processor (12 qubits) from Alpine Quantum Technologies (AQT).
Developers write CUDA-Q kernels once, select Scaleway as a backend, and seamlessly switch between large scale GPU emulation and production grade QPUs without modifying their code.
This removes the traditional barrier between experimentation and real world validation, allowing ideas to move from simulation to hardware in a single workflow.
By combining HPC grade emulation and multi modal quantum hardware under one Quantum as a Service interface, Scaleway establishes itself as Europe’s leading multi modal quantum cloud aggregator.
Strengthening Europe’s Quantum Ecosystem
Hybrid quantum cloud platforms are becoming a strategic component of next generation computing, linking artificial intelligence, scientific research, and industrial innovation.
By integrating CUDA-Q natively within a trusted European cloud, Scaleway provides the first European alternative combining large scale emulation and multi modality quantum hardware access on a single platform. In addition, Scaleway provides the most powerful state vector emulation up to 38 noiseless qubits achieved thanks to NVIDIA Blackwell Ultra.
“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”, said Sam Stanwyck, Director of Quantum Product at NVIDIA.“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.”
