TauZero,

Yes, double slit interference happens with both photons and electrons, and even with C60 buckyballs and organic fluorescent dye molecules (arxiv.org/abs/1402.1867)! This post is more so about the quantum eraser, as a counterpoint to the 12 posts about it that @kromem wrote in the other thread. The first experimental quantum eraser paper from 2001 uses photons, so that’s the figures I used here. There might be newer papers that use electrons, like this one doi.org/10.1126/science.1248459 from 2014, but I don’t have access to it. I presume detecting the electron there using induced current or whatever would disturb its wavefunction to the same severity as using the polarizer filter does here.
