From March 17 to 20, 2026, a group of researchers, PhD students, and administrative staff from ISSP and RTU visited the University of Technology of Troyes (UTT) for a training visit. During the event, experienced scientific and administrative personnel from UTT gave a series of lectures and organized in-lab practical training sessions. The following topics were covered during the four-day visit:
• Weak and Strong Coupling in Hybrid Plasmonic Nanosystems
• Introduction to numerical methods in photonics
• Quantum technologies using photons
• Imaging techniques for nano-object characterization
• Electric (and future optical!) addressing of Ln On-Surface
• Practical training: Entangled photon source, Optical tweezers, Optical alignment techniques, Introduction to quantum cryptography
• Administrative training: Research Office and Innovation Office at the UTT, CNRS technology transfer; Open science in projects; How to put up an MSCA proposal; Project writing.
We thank the prof. Christophe Couteau and his colleagues for the warm welcome and organization of the event. The personnel of ISSP and RTU gained valuable insights into establishing an internationally recognized research center that will support the main objective of the ToEQPL project.
