Shooting a Single Photon [duplicate]

How is it even possible that a single photon can be isolated and "shot" through a slit? What tool or mechanism or setup allows such an incredible feat, especially since the photon has no mass?

How can i only shine/shoot one proton/electron per second? [duplicate]

I would like to test out the two slit experiment but only one electron or proton at a time. This question is different from the rest that people are saying are duplicates as I am clearly asking how ...

“Firing one photon” [duplicate]

In the double-slit experiment, the "observer" is the one actually firing one photon. How does the observer fire one photon? Does not one have to "observe and "measure out" a single photon? How does ...

How does one detect a single photon?

I understand the double slit experiment up until the point that we begin "detecting" single photons. What does it mean to detect. You cant place a camera in the slit because that would capture the ...

Double Slit experiment with just one photon or electron

I just recently watched a video where they were explaining the double slit experiment. I understand that the interference pattern would be observed if you send photons or electrons one after the ...

Is double-slit experiment dependent on rate at which electrons are fired at slit?

I am a mathematician and I am studying string theory. For this purpose I studied quantum theory. After reading Feynman's book in which he described the double-slit experiment (Young's experiment) I ...

Shooting a single photon through a double slit

Consider the image below. It shows a double slit experiment but with a single photon at a time. My question is as follows: Why is it that the photons always take a different path when shot at the ...

In the “double-slit experiment” - did they actually shoot individual particles/electrons?

When describing the experiment - it is usually described that first, a wave was shot through two slits, than "individual particles" was shot through the slits (and then an interference pattern ...

photon wave function, double slit, single photon source

There's an old argument by Newton and Wigner, that the photon as a massless particle can't have a position operator and therefore no position space wave function. How does this tie in with the double ...

Double slit experiment with a single photon stream

I would like to know if the following are true: Each time you fire a single photon, only one dot appears on the back screen. Is there ever a case that while we are watching the experiment, that a ...

Is the double slit experiment performed measuring single photons?

As a hobby physicist I don't understand how the double slit experiment is performed in terms of single photons. Is the experiment really conducted by sending and measuring single photons? Is there not ...

Shooting a single photon (possible nowadays) will cause it to be the excitation of both Electric and Magnetic fields at the same position?

I understand that technology makes it now possible to shoot single photons. I have read this question, and the answers did not cover one thing. Single photons: Is there a 90° offset of the ...

Electron interference and light interference

In the double slit experiment, I see that shooting electrons one by one, with a time interval between them, eventually creates a pattern that resembles that of light interference. But, before the ...
