The 3-day doctoral training school (6-8 Oct) will involve 6 lecturers each giving a 3 hour “masterclass” to about 50 PhD students in quantum sciences. This school is called the Seminaire Dautreppe, and is an annual event (each year on a different topic) organized since 1969 by the Société Française de Physique. This year’s theme is the 2025 Unesco International Year of Quantum Sciences and Technologies.
