Quantum Computing Mobile XR Interface

Conceptual Architecture of the Quantum XR System covering the frontend and the backend components.Quantum computing is increasingly becoming a topic we are confronted with daily. This is mainly due to the problem-solving capabilities of the more readily available classical computers, which are not able to solve certain difficult problems in a shorter time and would take many years to obtain a solution. This has led to the massive development of quantum computers, but they are largely inaccessible. This inaccessibility is mainly due to the difficulty of maintaining them. Even though the main principles of quantum computers are known, the mechanisms such as quantum bits or gates are abstract. This raises the question of how content such as quantum circuits can be visualized understandably. Therefore, we developed an XR application with an easily accessible quantum simulation that allows the user to assemble different quantum circuits. The application itself would not offer a theoretical understanding of quantum circuits but would allow assembly of these with previously defined quantum gates. However, to get a better understanding of the quantum gates the simulation provides the vector state for each gate that has been used in the circuit. We evaluated the prototype with four participants. Within this online study, two participants evaluated the mobile Android app and two evaluated the Desktop application. The results show that the tool is perceived as promising, however, there is still a need for improvement in the area of usability to make the system easier to use.
