As strange as it may be to hear, the double-slit experiment conducted one photon at-a-time with "detectors at the slits" is nothing short of a myth. No such experiment has been reported in a peer-reviewed journal or any reputable book or publication. Talk of this supposed experiment, and even figures illustrating it, can be found throughout the internet, but ...

Any measurement you make at the slits is going to destroy the interference pattern. The wavefunction of the photon or electron collapses as soon at it interacts with the environment in a thermodynamically irreversible way. In essence, any type of measurement you could make that would tell you which slit a particle went through would cause the wave function ...

You can't detect single photons. There is no way to prove that a click in a photodetector represents a single photon versus the response of the system to an electromagnetic wave. There is no way to prove that the appearance of a fleck of silver on a photographic plate represents a single photon versus the response of the silver bromide crystal to an ...
