Quantum computing is a promising field but understanding how it works can be challenging for a beginner. There are also not many educational resources to visualize and learn about quantum computing. To advance knowledge in this area, we have created QubitVR, which employs a Bloch sphere representation of a qubit, and supports trajectory visualizations and state equations in a virtual reality (VR) setting. We also conducted a multivariate cognitive walkthrough with subject matter experts (SMEs) on QubitVR to assess the effectiveness of trajectory visualizations and state equations in learning about quantum gates. The results were that trajectory visualizations aided users in understanding and learning the outcomes of quantum gate applications, while state equations did not aid users in understanding or learning the outcomes of gate applications. This implies that when designing quantum educational applications, researchers should consider focusing on visual enhancements like trajectory visualizations while avoiding mathematical representations accompanying the Bloch sphere.
