What Quandela does
Quandela is a French full-stack photonic quantum computing company, founded in 2017 and headquartered in Massy, with a workforce of 130-140+ across France, Germany, Canada, South Korea, the USA, and the GCC. The company designs and manufactures the entire photonic stack end-to-end: deterministic single-photon sources based on semiconductor quantum dots (Prometheus), quantum processors (Ascella, Belenos, Canopus), a modular data-center quantum computer (MosaiQ), a quantum random number generator (Entropy), the Perceval software development kit, the MerLin quantum machine learning library, and a cloud access platform. Its technology generates qubits as single photons emitted on demand, which are routed through programmable photonic circuits to perform quantum computation.
The company sells to enterprise and public-sector customers in finance, defense, energy, and high-performance computing, with named clients including Crédit Agricole CIB, Safran Tech, EDF, CEA TGCC, BTQ Technologies, AdvanThink, and OVHcloud, plus 2,439 active cloud users. Revenue mechanics combine hardware sales (on-premises quantum systems), cloud access subscriptions, and bespoke quantum-acceleration programs delivered to enterprise R&D teams. Distribution is increasingly channel-mediated through partnerships with NVIDIA (NVQLink integration), OVHcloud, Exaion, Scaleway, and Sopra Steria, embedding Quandela's hardware into mainstream European HPC and sovereign-cloud procurement. The company has raised more than $60M in cumulative funding, with strategic backing from Crédit Mutuel Innovation, the European Innovation Council, and Serena Capital.

Product offeringCore offering
Quandela designs, manufactures, and sells full-stack photonic quantum computing systems, including the MosaiQ platform and the Ascella, Belenos, and Canopus quantum computers, as well as the Prometheus solid-state single-photon source. The company delivers these systems via on-premises hardware, cloud access (Quandela Cloud, OVHcloud Quantum Platform, EuroHPC), and complements them with the Perceval and MerLin open-source software frameworks, the Entropy quantum random number generator, the Quantum Toolbox of algorithmic primitives, and the Quantum Acceleration Program enterprise consulting service.
Product overview
Quandela is a global leader in full-stack photonic quantum computing, offering a unified platform-plus-modules architecture. At its core is MosaiQ, the flagship photonic quantum computing platform that delivers universal manipulation of pure, high-quality, on-demand photons and hosts the company's industrial-grade quantum computer systems (Ascella, Belenos, Canopus, and the EuroHPC-deployed Lucy/MOSAIQ-12). The platform is complemented by Perceval (open-source Python SDK for photonic quantum circuit design), MerLin (PyTorch-based framework for photonic quantum machine learning with hardware-aware MerlinProcessor interface), and the Quandela Hub developer portal. Solutions built on this hardware/software foundation include the Entropy quantum-certified random number generator, the Quantum Toolbox of packaged algorithmic primitives, the Quantum Acceleration Program consulting engagement, and Cloud Offers that deliver Quandela's QPUs and simulators as a service through OVHcloud and other partners, as well as direct access via the cloud.quandela.com platform. At the hardware level, Prometheus provides the standalone quantum-dot single-photon source technology underlying the company's photonic qubits, while the company's spin-photon architecture combines photons with semiconductor spin-based logic to target future fault-tolerant, utility-scale systems (as validated through DARPA's QBI Stage A selection).
