# Computational Projects » 1-Dimensional Demo of Entropic Quantum Dynamics

This is a demonstration of the concepts found in entropic quantum dynamics. [1,2] The plot area has three panes. The different quantities that can be plotted in each pane are listed above them. The third pane shows the expectation values of the velocities in the second pane. The problem is actually solved using the standard Schrödinger equation with the finite difference method. [3] The differential equations in EQD don't appear to behave well enough to be solved with standard numerical methods. As a consquence, the phase (and entropy) has lots of ugly jumps. I'm hoping to find a solution to this soon. Plotting is done using HTML Canvas. If you have any questions, comments, or suggestions, please contact me.
