Is the generation of one electron at a time probabilistic or deterministic ?

Click For Summary

Discussion Overview

The discussion revolves around the nature of electron generation and detection in the context of the double slit experiment, specifically whether this process is probabilistic or deterministic. It explores the mechanisms of generating single electrons or photons and the implications for experimental setups.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Some participants question whether it is possible to deterministically generate one electron at a time, comparing it to a gun that fires a single shot.
  • Others inquire about the feasibility of generating and detecting electrons or photons at a specific rate, such as 1000 photons per millisecond.
  • One participant asserts that generating single photons and electrons "on command" is possible, noting that double-slit experiments with single photons are routine.
  • Another participant mentions that generating single electrons can be achieved using an electron pump, although they are unsure if this has been applied in double slit experiments.
  • A later reply references a video of a single electron double slit experiment, highlighting that electrons are detected at random times and raises questions about the behavior of electron charge on the detector's surface and the possibility of simultaneous detections.

Areas of Agreement / Disagreement

Participants express differing views on the determinism of electron generation and detection, with no consensus reached on whether the process is inherently probabilistic or deterministic.

Contextual Notes

There are limitations regarding the assumptions about the nature of electron detection, the conditions under which electrons are generated, and the specifics of experimental setups that remain unresolved.

In the double slit experiment sometimes it is claimed that one electron at a time could be fired.
Can we deterministically generate one electron when we want ?
is it like a gun where you pull the trigger and exactly one electron will be detected or is it that we energize some source and "wait randomly" until we detect an electron coming out of it?

In other words, could we generate and detect electrons or photons (for that matter) at a specific rate? Say 1000 photons per millisecond.
 
Yes, it is possible (but not trivial) to generate both single photons and single electrons "on command" and double-slit experiments with single photons are more or less routine nowadays.

Generating single electrons is not very difficult in an electric circuit (using an electron pump); although I don't know of anyone has actually performed a double slit experiment using such a source (although my guess would be that it has been done).
 
Thanks for answering f95toli,
If you watch the video of the single electron double experiment performed by Hitachi
http://www.hitachi.com/rd/research/em/doubleslit.html
video here

and more clearly here:
http://www.hqrd.hitachi.co.jp/rd/moviee/doubleslite.mpeg

You notice that before they speed up the video, electrons are detected at random times. I was wondering since electrons are transmitted at a fixed rate if some electron charge transmitted will hit the detector without triggering a detection on the detector(charge will stay on the detector's surface without being released) or also if a wave can trigger two detections at the same time. Hope my question made sense.
