Visual-graphic representations play a crucial role in teaching quantum physics (QP) by bridging abstract concepts and learners' understanding. Grounded in Ainsworth's Design Function Task (DeFT) Framework (2006), we developed a category system to evaluate the features of qubit representations. We had 21 experts from four different countries use this category system to analyze four qubit-representations bloch sphere, circle notation, quantum bead, and Qake model. Significant differences emerged in visualizing concepts such as quantum measurement, superposition, and probabilistic behavior. Notably, quantum beads were rated as significantly more salient, demonstrating strong potential to effectively direct learners' attention. The findings underscore the diversity and complexity involved in designing representations in QP and QT while laying the groundwork for further empirical research. Building on the expert evaluations, we are conducting a study to examine how salient representations, such as the quantum bead, influence learners task performance, cognitive processing, and learning outcomes compared to the Bloch sphere. Through expert evaluation and the follow-up study, this work seeks to improve teaching resources and advance understanding of QP and QT.
