If you want to play with quantum wave packets, I built a quantum Web-based Simulation tool for non-relativistic quantum mechanics in 2016: https://quantum-simulation.de https://quantum-simulation.de The split-operator method for the numerical solution of the time-dependent Schrödinger equation is used to simulate the propagation of a Gaussian wave packet in arbitrarily adjustable potentials.
