Quandela stands as a global leader in quantum computing, driven by groundbreaking technology and a strategic vision for scaling quantum solutions. The company’s unique ability to offer both hardware and software solutions, along with its commitment to build energy efficient datacenters and scalability, positions it to play a key role in the next wave of innovation, and in many strategic and sovereign industrial sectors.
Join Us at the Forefront of Quantum Computing Innovation 🚀
We are the company’s forward-guard, working to identify the best paths forward for our technology, its architecture, and its applications in quantum computing. We study hybrid spin-optical architecture, fault-tolerance, logical gates, magic states and we push the limits of Quandela's technology.
This internship aims at developing novel fault-tolerance strategies for Quandela's SPQOC architecture.
The project explores how this architecture could be extended with high-rate quantum codes to improve encoding density without sacrificing reliability or computational flexibility.
Develop practical experience with simulation of fault-tolerant circuit, quantum LDPC codes, and architecture design.

Quandela builds full-stack photonic quantum computers in France, including on-premises MosaiQ hardware and cloud access to its processors. It uses semiconductor quantum-dot single-photon sources to create bright, indistinguishable photons that act as optical qubits, with Perceval, an open-source Python framework, for simulating and programming photonic circuits, and Prometheus, a standalone single-photon source for research labs. The company differentiates itself by offering end-to-end hardware, software, and services—from production in its own facilities to cloud access and an acceleration program that guides clients from use-case exploration to hardware delivery. Its goal is to help clients achieve practical quantum advantages across industries such as cybersecurity, energy, finance, logistics, chemistry, and pharmaceuticals.
