No. While understanding quantum principles helps, our platform is designed for developers. We support standard, high-level open-source SDKs (like Qiskit, Cirq, and PennyLane) that abstract much of the physical complexity. You can start coding in Python immediately using familiar libraries.
Real quantum hardware is a scarce and valuable resource. Our GPU-accelerated emulators act as a "Digital Twin," allowing you to prototype, debug your code, optimize circuit depth, and validate results at no noise. This ensures that when you do reserve a real QPU, every shot counts.
Logical qubit is an abstract information storage built to be fault tolerant and time resilient to quantum operations. It is built on a set of hundreds or thousands of physical qubits. Physical qubits tend to be closer to the quantum material and more unstable.
We offer a flexible model tailored to your usage.
Yes. Scaleway is a European cloud provider. Your data, your code, and your results are hosted in our data centers within the European Union, protected by strict EU privacy laws. We provide a sovereign alternative to non-EU hyperscalers, essential for sensitive research and industrial applications.
Absolutely. This is the core of our "hybrid" approach. You can trigger quantum jobs from your existing Scaleway Instances or Serverless Functions, store input/output data in Object Storage, and process the results using high-performance classical CPUs or GPUs.
For emulation and "pay-per-shot" QPU access, provisioning is almost instant. For dedicated QPU reservations (Quandela or IQM), slots are booked via our console. We recommend booking in advance for specific hardware to guarantee availability for your experiments.
