Join Us at the Forefront of Quantum Computing Innovation 🚀
Description of the Team/Project
MerLin is a photonic quantum machine learning framework that brings quantum computing capabilities to AI practitioners through familiar PyTorch integrations. The internship will contribute to the development and scientific validation of MerLin by either reproducing recent quantum machine learning papers with the framework, or by improving the core codebase directly. Depending on the candidate profile and project priorities, the work may include implementing research models, building clean examples and benchmarks, extending model APIs, improving tests and documentation, or contributing to performance and usability improvements. The goal is to produce concrete, reviewable contributions that strengthen MerLin as a research and engineering tool.
Possible Missions
- Reproduce selected quantum machine learning papers using MerLin, with clear notebooks, benchmarks, and documented assumptions.
- Implement or improve quantum-classical model components in Python, PyTorch, and the MerLin codebase.
- Compare reproduced results against published baselines and identify gaps due to simulation choices, datasets, or implementation details.
- Add tests, examples, and documentation so new features are maintainable and usable by researchers and ML practitioners.
- Contribute to code reviews, issue analysis, experiment tracking, and technical reports summarizing results.
What you will learn:
How to connect research papers to production-quality scientific software.
How photonic quantum circuits can be integrated into PyTorch-style machine learning workflows.
How to design experiments, benchmarks, and tests for hybrid quantum-classical models.
How to contribute to an open-source-style Python project with reviews and continuous integration.
Master 1 or Master 2 student, engineering school student, or equivalent, with a strong background in machine learning, software engineering, applied mathematics, or computer science. This position is only valid with an Internship Agreement
Solid Python skills and practical experience with scientific computing and machine learning tools such as NumPy, PyTorch, Jupyter, and Git.
Good understanding of machine learning workflows, including model implementation, training loops, datasets, evaluation, and reproducible experiments.
Interest in quantum computing, photonics, or quantum machine learning is appreciated, but prior quantum expertise is not required.
Ability to read technical papers, translate algorithms into maintainable code, and clearly document experimental assumptions and limitations.
Careful engineering habits: tests, reproducible experiments, readable code, and comfort working through pull requests.
