Okay, let's take the interactions in a standard double split.
Wavicle is emitted. It is not detected at first screen so must have passed through slits. The interaction of the waveform from both slits can then be used to make predictions about the likelyhood of finding a particle at any point. Once the second screen registers an impact the probability of finding it anywhere else is zero. This is not time invariant. At one instant there is a non zero probability space filling waveform, the next there is not. Reversing this doesn't isn't possible. Of course neither is measuring this probability wave. I guess the only question is if you saw a particle leap off the rear screen, and saw it arrive at the `source` could you tell this was time reversed, and the answer would be no.
I'm not trolling here, I genuinely understood that the collapsing waveform is not time reversable.
