On 6 May, CERN hosted its first-ever workshop for high-school students on all things quantum. The event was organised jointly by CERN’s Quantum Technology Initiative (QTI) and Finland’s QPlayLearn team in the context of World Quantum Day 2023. A total of 30 enthusiastic students from local schools in France and Switzerland attended the workshop. During the half-day event, the students, aged 15 to 18, were introduced to the fascinating field of quantum science and technology. The workshop kicked off with a lecture held in French by Su Yeon Chang, a doctoral student in quantum computing at CERN. In her lecture, Chang explained what quantum physics is and how its fundamental concepts work. She also covered the basic principles of quantum computing and its potential and current challenges. An interactive “Learn-by-Play” session followed this introductory lecture and was set up as a tournament. Split into small groups of three, the students rotated through seven quantum-gam
