Coincedence Counter in Double Slit Experiment?

[Jamesc320010]

I have what I believe is a simple question about the single photon (at a time) double slit experiment. This experiment does not use a coincidence counter correct? I understand that one, or more, is used for entanglement experiments, but is one necessary to determine an interference or lack of interference pattern?

Welcome to PhysicsForums, Jamesc320010!

You are correct: no coincidence counter is needed to see an interference pattern from single photon interference.
