交互式计算机模拟中的可视化是帮助学生开发富有成效的心理模型的强大工具，特别是在没有经典模拟的量子现象的情况下。QuVis量子力学可视化项目为量子力学的学习和教学开发基于研究的交互式模拟。我们描述的努力，以改善在QuVis模拟的单光子叠加态的视觉表示。我们开发了不同的光子入射到分束器的解释，并通过个别访谈调查了它们对学生思维的影响。这项研究的结果导致在所有QuVis单光子模拟中纳入了经修订的可视化。在2013年和2014年的课堂试验中，在量子物理学入门课程中使用干涉仪实验模拟，用于对初始和修订后的可视化进行比较研究。使用修改后的可视化的班级显示出关于量子叠加的不正确想法的频率较低，例如光子分裂成两个半能量分量。
Visualizations in interactive computer simulations are a powerful tool to help students develop productive mental models, particularly in the case of quantum phenomena that have no classical analogue. The QuVis Quantum Mechanics Visualization Project develops research-based interactive simulations for the learning and teaching of quantum mechanics. We describe efforts to refine the visual representation of a single-photon superposition state in the QuVis simulations. We developed various depictions of a photon incident on a beam splitter, and investigated their influence on student thinking through individual interviews. Outcomes from this study led to the incorporation of a revised visualization in all QuVis single-photon simulations. In-class trials in 2013 and 2014 using the Interferometer Experiments simulation in an introductory quantum physics course were used for a comparative study of the initial and revised visualizations. The class that used the revised visualization showed a lower frequency of incorrect ideas about quantum superposition, such as the photon splitting into two half-energy components.
