Quantum Composer is an interactive tool for visualizing and simulating quantum mechanical concepts and systems. It consists of a graphical user interface where one can drag-and-drop nodes to create a flow-based simulation. The powerful and versatile quantum visualizations make it relevant for use in education and research. We provide a suite of exercises suitable for students from high school through to the graduate level.
