In the first week of May, the QLSI2 consortium gathered for its third General Assembly at the MINATEC innovation campus in Grenoble, France. Hosted by CEA-Leti, the event brought together representatives from the project’s 23 partner organizations to review technical progress and align on the roadmap toward 2027 for the development of quantum computing with semiconducting QPUs.

The role of OrangeQS
OrangeQS supports TNO in deploying a SiGe semiconductor spin qubit quantum computer into the Quantum Inspire platform and enabling 24/7 public cloud access to this system. As part of this effort, OrangeQS is developing an automated calibration graph for the early stages of tuning quantum dot devices, with the aim of structuring and simplifying a process that is typically time-consuming and reliant on expert input. By working on improving the efficiency and consistency of the calibration process, OrangeQS helps ensure that the underlying hardware can be reliably accessed and operated through this ecosystem.
Overall, the goal is to make the calibration workflow more fluid and efficient by reducing the need for manual intervention. This contributes to scaling the system’s operation and supporting broader access to advanced quantum hardware through the House of Quantum and its public-facing quantum experience center.
Technical Progress and Roadmap Alignment
The plenary sessions focused on the latest developments in semiconducting Quantum Processing Units (QPUs). Partners presented updates on the two main technological approaches pursued within the project: FD-SOI and SiGe heterostructures. These discussions support the consortium’s goal of delivering a 200-qubit semiconductor-based quantum computer that can be accessed via the cloud by the end of 2027.
Key topics addressed during the workshops included:
- Scalability: Advancing technology and manufacturing readiness to meet industrial requirements.
- Design and Fabrication: Characterizing QPUs to ensure performance across the proposed 200-qubit size.
- European Supply Chain: Designing the framework for a sovereign ecosystem in the production of QPUs.
Communication activities and expert insights
Communication activities were also part of the program. A series of interviews with experts from across the consortium was recorded on site. These recordings are intended for both scientific and industrial audiences, highlighting recent progress in FD-SOI and SiGe technologies and outlining their potential for large scale quantum computing.
Strengthening the Partnership
Alongside the formal program, the General Assembly created space for informal interaction. A social gathering provided an opportunity to exchange ideas on technical challenges and collaboration approaches in a more relaxed environment, supporting stronger connections across the nine participating countries.
By combining expertise from research and technology organizations, universities, and industry partners, the QLSI2 project continues to contribute to Europe’s role in advancing quantum technologies.
