This study presents the design and implementation of a university course for physics teacher training with a focus on quantum technologies and quantum information science. The course aims to equip prospective teachers with the knowledge and skills to teach quantum physics at upper secondary level and provide their students with insights into the professional world of quantum technologies. To this end, the course comprises three parts: a theoretical seminar at university, a didactic internship at quantum technology companies and a transfer phase implementing corresponding teaching units at school. The course was developed and implemented in several cycles within the framework of design-based research. The effect of the course was evaluated by an exploratory interview study. The focus was on its impact on prospective teachers’ attitudes and knowledge concerning quantum technologies, as well as on the implementation of career-oriented teaching units in the classroom. The results show that the internship was considered interesting and motivating by the prospective teachers, who valued the opportunity to gain insights into professional fields. However, transferring the content and experiences from the internship into actual school practice proved to be challenging. This process was perceived as difficult and required extensive support from university supervisors. From the results it can be concluded that the approach achieves its aims of providing prospective teachers with an introduction to quantum technologies and related professions and of stimulating students interest in the subject.
