I'm working on an animation engine to animate quantum circuits shadowing off Grant Sanderson's incredible animation library Manim.
ManiQ will be equipped with interactivity -- allowing users to build their own quantum circuits and visualize them executing in an aesthetic manner.
I hope to add features to allow users to visualize a statevector's evolution as the circuit runs for educational purposes. In addition, I'll add features to visualize measurement probabilities, density matrix(es) updating in real time, entanglement and much more.
Thank you for checking this project out. Once it gets up and running I'll make it open source.
