Well, as soon as you "observe" it, the wavefunction collapses. In this experiment, they observe it way after it passes through the slits, so the quantum can pass through both slits.
If you observe it before passing, if that's possible, the wavefunction will collapse at that moment, and the quantum will pass, like a particle, through a single slit.
No idea how it would be possible to observe it mid-flight though.

- judofyr 15y agoI think he mixed up the observation and the conclusion/interpretation: Well, as soon as you "observe" it, we will no longer see an interference pattern
- ovi256 15y ago>Well, as soon as you "observe" it, we will no longer see an interference pattern That's not strictly true, because the experiment is observing the quantum, and it is seeing an interference pattern. The critical thing is that they're observing it after the quantum has gone through the slits, so as it passes through the slotted wall, it's wavefunction is not constrained. So the moment of observation is very important.
