An electron’s wave function propagates in time from its starting h-bar shape to a complicated mess. The material in which the wave propagates is modified so that electron is briefly trapped. When the material is returned to its normal state, the wave propagates as if it were moving backwards in time, and returns to its h-bar original shape.
