This experiment seems to be really hard to do, and so there aren't many super clear demonstration videos with full experimental setup description out there unfortunately.

Wikipedia has a good summary at: https://en.wikipedia.org/wiki/Double-slit_experiment#Overview

For single-<photon> non-<double-slit experiments> see: <single photon production and detection experiments>. Those are basically a pre-requisite to this.

<photon> experiments:
* https://aapt.scitation.org/doi/full/10.1119/1.4955173 "Video recording true single-photon double-slit interference" by Aspden and Padgetta (2016). Abstract says using <spontaneous parametric down-conversion> detection of the second photon to know when to turn the camera on

<electron> experiments: <single electron double slit experiment>.

Non-<elementary particle>:
* 2019-10-08: 25,000 Daltons
* https://interactive.quantumnano.at/letsgo/ awesome interactive demo that allows you to control many parameters on a lab. Written in Flash unfortunately, in 2015... what a lack of future proofing!

{description=Claims to do exactly what we want, but does not describe the setup precisely well enough. Notably, does not justify how he knows that single photons are being produced.}
