Quandela stands as a global leader in quantum computing, driven by groundbreaking technology and a strategic vision for scaling quantum computing. 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 🚀
Could a nitrogenase-inspired catalyst enable more sustainable ammonia production? Could RSA-2048 be decrypted by 2032? Answering questions such as these requires careful quantum resource estimation: determining the hardware resources needed to run a given algorithm on Quandela’s spin-optical quantum computer.
During this internship, your main objective will be to perform a thorough resource estimation, including detailed compilation, for a commercially relevant problem. You will estimate the required quantum hardware resources, including component counts and QPU size.
You will join Quandela’s AI, Algorithms and Applications (AIps-AI) team. The team develops fault-tolerant algorithms and estimates the resources required for running them on large-scale quantum computers, uses AI to develop software tools and improve QPU performance, runs near-term quantum machine-learning algorithms on real devices, and supports customers with application development.
We do not expect you to master all these topics. This internship is designed to be a deep dive into fault-tolerant architectures and advanced quantum algorithms, and you will actively develop these skills during your project. Any prior experience to the following areas is a strong plus, but not strictly required:
Swile Card (meal vouchers) 🍴🛒
50% participation in transportation costs 🚆
Possibility of remote work 💻
Internship Allowance between €1,200 and €1,400 per month 💰
1,5 days off per month, cumulative 🧳
What we also offer
A challenging and innovative work environment at the heart of quantum computing.
A diverse and collaborative company culture.
Opportunities for professional growth and skill development.
At Quandela, we believe that the strength of our team is the plurality of experiences, perspectives, and journeys. We are committed to building a respectful, inclusive, and welcoming work environment. All applications are welcome.

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.
