Quandela QPUs Information
Developed by Quandela, a French quantum computing leader founded in 2017. Their technology is based on Linear Optical Quantum Computing (LOQC), utilizing proprietary single-photon sources and reconfigurable optical circuits to process information at room temperature.
Key features
- Room temperature operation: Unlike many quantum technologies that require cryogenic temperatures, Quandela's photonic QPUs operate at room temperature, simplifying infrastructure needs.
- All-to-All connectivity: The photonic qumodes are interconnected through linear optical components, allowing for flexible circuit designs and
- Linear optical computing: Utilizes single photons to process information through reconfigurable optical circuits, operating largely at room temperature (chip-level).
- High-Quality Sources: Powered by proprietary high-performance single-photon sources, ensuring indistinguishable photons for high-quality interference.
- Native probabilistic computing: The hardware natively implements sampling tasks, making it inherently suited for probabilistic modeling.
Use cases
- Quantum Machine Learning (QML): Ideal for generative modeling, classification, and training quantum neural networks (QNNs).
- Certified randomness: Generation of high-quality entropy for cryptography and stochastic simulations.
- Sampling tasks: Efficiently performs sampling from complex probability distributions, useful in various scientific applications.

Perceval: The native SDK for photonic
Perceval is the open-source software framework created by Quandela for linear optical quantum computing. It provides a simple and powerful object-oriented API to:
- Design - linear optical circuits (Beam Splitters, Phase Shifters, etc.).
- Simulate - photon behavior (ideal or noisy simulation).
- Execute - algorithms on various backends: local simulators, high-performance remote simulators (on GPU), or real photonic QPUs.
On Scaleway QaaS, the integration is natively integrated into perceval-quandela package, which acts as a remote backend for your sequences.
