If you have a probability distribution of position.
Then increment time by one tick. If you have a second probability distribution (assuming some time dependence) then you have now a distribution of distance travelled and therefore a distribution of speeds.
The alarming thing about QM is that it is fundamentally probabilistic and yet a little classical at the same time.

- AnimalMuppet 6y agoI don't think that's right. If you increment the time by one tick, you have the same position probability distribution. That is, the wave function didn't change. Why should it? But that position probability distribution has a very specific energy. And at each point of that position distribution, the electron has a specific electrical potential energy. So at each point, it also has to have a kinetic energy. It has a kinetic energy probability distribution to match the position probability distribution. And now we can talk about velocity.
