As quantum technologies increasingly impact society and the workforce, there is a growing need to integrate quantum physics (QP) education into all levels of the curriculum, including secondary education. However, despite increasing interest, there is little consensus on which topics should be covered and to what depth. This study addresses this issue by exploring experts’ perspectives on the future of QP education at the secondary school level. Using an adapted Delphi method, we conducted three rounds of surveys with a diverse panel of quantum physics and physics education experts. The study aimed to identify the most appropriate QP concepts for inclusion in secondary school curricula and the instructional level at which they should be taught. The findings show strong expert support for including foundational QP topics, such as quantum interference, superposition, and quantum measurement, taught at a conceptual rather than a mathematical level. More advanced topics related to quantum technologies were widely deemed unsuitable for the secondary school. These results are consistent with existing national curricula and provide valuable insights into current perspectives on QP education, reinforcing the importance of core quantum physics concepts in secondary education. These insights lay the groundwork for further research into the future direction of quantum education and support the integration of quantum technologies into secondary school curricula.

[This paper is part of the Focused Collection in Investigating and Improving Quantum Education through Research.] Teaching quantum physics (QP) to high school (HS) students is gaining momentum, necessitating the exploration of various effective methods. Specifically, the research on quantitative teaching methods is still in its early stages. Understanding the power of Dirac notation (DN) in teaching is crucial for grasping the complexities of QP, as it provides a concise and powerful symbolic framework that facilitates both conceptual and computational understanding. This study investigates the proficiency of HS students in interpreting, producing, and manipulating DN within QP. Utilizing qualitative content analysis of student responses to various tasks, quizzes, and final tests, the study aims to uncover the sensemaking opportunities DN provides and the difficulties students encounter. The findings indicate that DN facilitates both conceptual understanding and quantitative problem solving in QP by enabling students to interpret and produce representations of quantum states. The results highlight the importance of extensive practice and well-structured teaching sequences in developing DN proficiency, reinforcing the role of DN as an effective tool for teaching QP at the HS level. The study contributes to the ongoing discourse on integrating mathematical modeling in physics education, emphasizing the potential of DN in enhancing students’ grasp of QP concepts and their application in problem solving.

Quantum Key Distribution (QKD) is a cryptography protocol based on the fundamental principles of quantum physics (QP). Teaching this subject does not require extensive knowledge beyond these principles, making it suitable for inclusion in high school (HS) curricula. Despite its relevance, teaching QKD in HS is yet understudied. In this study, we collected responses from 12th-grade students from various schools that adopted and applied the Discipline-Culture vision of the physics curriculum. We assessed their understanding through conceptual and quantitative problems and examined their attitudes regarding the motivation to study this subject. We analyzed the responses using content analysis, identifying the challenges and affordances of teaching QKD. The challenges faced by students have been categorized into three themes: difficulties with QP, difficulties with the QKD protocol, and difficulties with the mathematics involved in this context. Despite these challenges, we found that teaching QKD reinforces students’ conceptual understanding of QP concepts and problem-solving skills. This work enhances educators’ ability to address the challenges of teaching QP and suggests that teaching QKD in HS strengthens students’ motivation to study QP.

The goal of teaching quantum physics (QP) in high school is a problematic and highly turbulent area of divergent views, curricula studies, and claims. The innovative curricular approach of discipline-culture (DC) suggests a way of overcoming its significant difficulties. It suggests presenting QP as a fundamental theory structured in terms of the nucleus, body, and periphery. Applying this perspective in our study, we interviewed nine experts with respect to their view of how the nucleus of QP should be presented to high-school students. With the different viewpoints of the core essentials in hand, we compiled the nucleus of the QP. We also examined this subject using nine introductory university textbooks that might suit high school students and considered their coherence and suitability with regard to the specified nucleus. We found some confusion regarding the status of theoretical items: some fundamental principles, as perceived in the eyes of the experts, are presented as phenomena. Not only does this mismatch represent a special barrier for both the teachers and students to understand QP, it promotes an inadequate image of QP as well as a distorted view of the nature of science. Finally, we offer a framework for a DC-based QP curriculum free of the noted deficiencies.
