## Main Question or Discussion Point

I was wondering if it would be feasible to set up something like the following experiment to validate the pilot wave theory. The idea here is to set up a double slit experiment, but control the initial conditions of photons emitted from a source (i.e., their directions) such that one can specifically target a particular slit (of the two slits).

According to the pilot wave theory, since one has both a particle and a pilot wave for each photon, it seems that one should be able to aim the particle part of the photon precisely enough at the middle of a particular slit, such that the particle MUST pass through the slit. Although the experiment is done with two slits, one should end up with a non-interference pattern at the detector.

According to the Copenhagen interpretation, each photon should travel as a wave, and therefore, no matter how accurately one aim's the photons, one should still end up with the interference pattern. Since there are no hidden variables - no amount of directional adjustment should erase the interference pattern.

------------------

So, my question is: Does the above experiment make any sense?

Is setting the initial conditions of the photons equivalent to a "measurement" and "collapsing the wave function? (i.e., forcing the photon to travel as particles)? Obviously, the experiment won't work if this were true. Or is there a possible way to set the directions of the photons but NOT collapse the wave function?
