Inria is organizing a forum on open-source quantum software for research taking place on 5-7 October, 2026 at Inria Paris.
Talks can be attended remotely and will be recorded. Join the talks online.
| Important dates | |
|---|---|
| Forum | 5-7 October 2026 |
| Hackathon | 6 October 2026 |
We invite all researchers, engineers and students interested in learning about and contributing to the rapidly evolving open-source quantum software ecosystem to take part in this forum.
Participation is free of charge, and lunch, coffee breaks and a social dinner will be provided by the organization.
The afternoon of Tuesday, 6 October will be devoted to a hands-on hackathon, giving participants the opportunity to contribute to open issues in open-source quantum software projects, work directly with project maintainers, and connect with fellow developers and researchers. For more information, see here.
You may find a detailed program with information on the featured talks here
Registration is now closed. Yet, if you would like more information about the event, feel free to contact us at: rt-quantum-orga@inria.fr.

The research community in quantum computing remains mostly focused on physical aspects and theoretical computer science (cryptography, complexity theory, algorithms, etc.). The “software engineering” dimension is often underrepresented.
The national quantum strategy aims to support large end-to-end projects: after the initial phase of scientific momentum building, we are now reaching a stage where these projects are mature enough to engage in software development, in particular through the national hybrid computing platform HQI. This is necessary for several reasons:
The objectives of this forum are as follows:
Below is a non-exhaustive list of topics we plan to cover in the featured talks and discussions:
In 2024 and 2025, we organized the Graphix workshops (supported by external funding). This workshop is closely tied to the development of the Graphix library, and we believe this format can benefit a broader community whose software development activity is not yet well structured.
The originality of these workshops lies in combining scientific talks with co-development (“hackathon”-style) sessions. This format helps engage a community that is often distant from software engineering concerns, and it helps establish a state of the art around algorithmic questions, computational modeling, and open problems linked to software development activities.
In addition, the Inria EQIP challenge (Engineering for Quantum Information Processors, 2021–2024) structured efforts in quantum engineering through regular scientific meetings covering both software and hardware. Here, we aim to focus attention specifically on software, a dimension that is culturally underemphasized in a community largely composed of experimental physicists.
