e-DIAMANT Annual Report

The EquipEx+ e-DIAMANT consortium met on June 2 and 3, 2026, at the University of Versailles Saint-Quentin-en-Yvelines (UVSQ) to discuss the progress made by the various teams.

Led by Jean-François Roch, a lecturer-researcher at ENS Paris-Saclay at LUMIN, e-DIAMANT brings together the know-how and expertise of its 11 partners to create diamond samples optimized for quantum applications, specifically by utilizing diamond’s structural defects as quantum sensors based on artificial atoms.

Progress updates and discussions

The e-DIAMANT annual review began with a progress meeting attended by teams from the 11 laboratories involved in the infrastructure, namely:

CEA-LIST
Centre de Nanosciences et de Nanotechnologies (C2N)
Centre de Recherche et d’Enseignement des Géosciences de l’Environnement (CEREGE)
Centre de recherche sur les ions, les matériaux et la photonique (CIMAP)
Groupe d’études de la matière condensée (GEMaC)
Institut de Recherche de Chimie Paris (IRCP)
Institut Fonctions Optiques pour les Technologies de l’information (Institut FOTON)
Institut Jean Lamour (IJL)
Laboratoire Albert Fert (LAF)
Laboratoire de Probabilités, Statistique et Modélisation (LPSM)
Laboratoire Lumière-Matière aux Interfaces (LUMIN)

Jean-François Roch presented a second progress report, this time focusing on equipment and resources. The program also included a session at the end of the event for discussion with the ANR and partners.

Scientific Presentations

Cathodoluminescence Microscopy of NV Centers in Bulk Diamond and Nanodiamonds, Julien Barjon, lecturer-researcher at UVSQ, GEMaC
Controlled Generation of Magnetic Domains Induced by Femtosecond Pulses, Daniel Lacour, CNRS researcher at the IJL
Controlled Ion Implantation: From Individual to Collective Effects, Stéphane Guillous, CEA Engineer at CIMAP

All the participants were finally able to enjoy a tour of the GEMAC facilities.
