The Quantum Spin-Off project connects secondary school teachers and students with researchers and spin-off companies to teach modern fields like quantum physics and entrepreneurship. Funded by the European Commission, the project provides learning materials, teacher guidelines, and national teacher trainings. Teachers guide their students through scientific papers, experiments, lab visits, and developing ideas for socially useful applications. Students may enter a contest to win the Quantum Spin-Off Prize. Feedback from teachers is used to improve the program and ensure its sustainability.
