Interactive visualisation for teaching a quantum double slit experiment

Abstract

In teaching quantum physics, visualisation is a useful tool to improve students’ understanding of phenomena from the quantum realm. The double slit experiment has shown itself to be a good simple enough example where all important quantum concepts such as wave-particle duality, superposition, or measurement meet in a nice way. Compiling advantages of existing visualizations, we present a new simple web-based interactive interface visualising the double slit experiment with electrons suitable for high school level. Guidelines for using the visualization in classroom are also provided. Teachers and students would be able to conduct this experiment by themselves and explore behaviour of quantum objects step-by-step, following a path outlined by Richard Feynman in his famous lectures.
