Abstract
Quantum physics is considered one of the most conceptually challenging topics in physics education due to its abstract nature and incompatibility with classical deterministic intuition. This study aims to analyze the profile of students^ conceptual understanding of the basic concepts of quantum physics from deterministic, probabilistic, and intermediatic perspectives. This study uses a quantitative descriptive approach by involving students who take quantum physics courses. Data were collected through conceptual pre-test instruments that included wave-particle dualism, Bohr^s atomic model, photoelectric effects, and electron concepts, accompanied by students^ confidence levels in the answers given. Student responses are analyzed and categorized into deterministic, probabilistic, and intermediatic conceptual tendencies to identify patterns of conceptual understanding. The results show that students understanding of some quantum concepts is still dominated by deterministic reasoning, while probabilistic understanding still seems limited. On the other hand, the intermediatic tendency reflects the conceptual thinking transition between classical and quantum perspectives. In addition, students^ confidence levels in answers are not always in line with conceptual accuracy. These findings demonstrate the need for learning strategies that explicitly facilitate students conceptual transition from deterministic reasoning to probabilistic understandings that are more in line with the characteristics of quantum physics
