I'm thinking about the quantum double slit experiment. Specifically the part where if you had a detector pointing at one of the slits, this would collapse the wave function and the interference pattern would disappear.
I then watched a video about it that said something like "if you go and quietly pull the plug on your detector (trying to "trick" the experiment) then the interference pattern would return.
I understand this as a way to educate and explain the concept, but I thought that I had heard that the things that actually collapse the wavefunction are ambient photons interfering with the experiment - i.e. a stray photon would bounce off of the electron and scatter into the detector, giving us the information about what slit the electron went through.
So in practice, if you just unplugged your detector in your well-lit laboratory, I'm guessing that this wouldn't change the outcome of the experiment at all - there would already be no interference pattern because of the ambient photons.
Similarly, if you had a completely dark room devoid of photons, whether your detector was plugged in or not would make no difference, as if would not be able to "see" where the electron was and so there would be no interference pattern in either case (plugged in or not).
Is this the right way to think about things?
