Increasingly complete mastery of quantum systems requires the support of highly interdisciplinary scientific and technological resources, which cut across the different thematic areas and form the indispensable foundation. This includes both the development of theoretical methods, upstream knowledge promising new approaches, and the development of materials, integrated devices and enabling technologies essential to the realization of quantum devices. The efforts undertaken in this area will draw particularly on the industrial fabric of the Île de France region to benefit from the best technological innovations already available, and to inject a quantum dimension into future developments.
Objectives
- Theoretical methods. This area will encourage the development of new models and numerical and analytical tools that go beyond the usual approximations and take into account the specificities not only of the platforms but also of the technological goal pursued.
- New approaches. This area will support the exploration of new paradigms for quantum technologies, promising greater robustness of quantum information (e.g. the search for topological quantum systems and active stabilization processes for quantum information).
- Materials. The synthesis of very high-quality materials compatible with quantum technologies (“quantum grade”).
- Integrated devices. Design of appropriate architectures for qubit/photon and qubit/electronics interfaces, frequency conversion to the telecom band, hybrid quantum electronic circuits, etc.
- Enabling technologies.

The supercurrent through the wire depends on the spin of a single electron trapped in the semiconductor region. Photo: Marcelo GOFFMAN, CEA (2021).
