Does one see an interference pattern with single photons/electrons through a single slit?

I understand that diffraction patterns are seen with single slits with multiple photons/electrons, due to Fraunhofer effects. But do multiple single photons/electrons produce the same pattern, as they would in the double-slit experiment? (i.e. single photon detections aggregated over time)

• As far as I know this was one of the big flags for the wave-particle duality of electrons. They could shoot them one by one and still ended with a diffraction pattern.

• Hi. This was certainly the case with the double-slit experiment but was it also seen in the single-slit case? May 3 '17 at 12:02
• Do you have any reason to believe it would not? Just showing your thought process gives others a way to address the motivation for the question.

• This is done by using a very low flux. Given the speed of light, if you are sending (say) 1000 photons per second through the aperture, and you consider "at the same time" to be "they are within 1 mm of each other when they go through", then they need to be arriving within 3 ps ($\tau$) of each other. The probability of that happening (if the N=1000 are randomly distributed) is $2\tau N^2$ - there are $N$ intervals of width $\tau$ that can overlap with each other. That is clearly a very small number... so the vast majority of photons making up the pattern came through "one at a time". May 3 '17 at 12:49
