고등학교 양자역학 교수학습의 재구성: 역사적 접근의 한계와 단일양자 이중슬릿·광자 큐빗 기반 현대적 접근

초록

This study examines changes in the teaching of quantum mechanics in the 2022 revised curriculum and analyzes their educational implications. It first critiques the traditional historical approach, arguing that the compression of conceptual development often results in distortions such as conflating energy quantization with wave–particle duality. As an alternative, the study proposes a modern instructional approach centered on the single-quantum double-slit experiment, which enables the integrated treatment of the de Broglie relation, Born’s probabilistic interpretation, superposition, and measurement-induced state change within a unified context. Finally, the study discusses the use of photon polarization as a qubit model for introducing quantum technologies. By connecting single-photon polarization measurements to Malus’s law, classical continuous behavior can be related to quantum probabilistic events, while the B92 protocol provides an accessible framework for introducing the core principles of quantum cryptography at the high school level. © (2026), (Korean Physical Society).
