In the single-shoot, double slit experiment, does the screen register one corresponding particle for each one fired or more than one each time?

Question

This info is crucial for my research. Are there any experimenters here who actually did the experiment and can confirm if this is the case?

It measures one each time. This is fundamental to quantum mechanics and the idea of a photon. Are you having doubts that such experiments have been done? The Photoelectric Effect is also relevant. — mmesser314, Mar 07 '21 at 15:11
Why do you think the particles might multiply between source and target? Can you suggest an experiment to test that hypothesis? — Guy Inchbald, Mar 07 '21 at 16:06

Photons are quantum mechanical entities, and in the famous double slit experiment, these photons are shot one at a time. Each time you shoot a photon, there will be one single dot on the screen.

Any photon that gets past the slits will make at most one mark on the detector, but the detector probably is less than 100% efficient, and some photons may fail to leave a mark.

In a double slit experiment, does each and every photon leave a dot on the screen in the bright area?

So the ultimate answer to your question is yes, one photon shot at a time will register one single dot on the screen (except if no dot, because of experimental error).

In the single-shoot, double slit experiment, does the screen register one corresponding particle for each one fired or more than one each time?
