Discussion Overview
The discussion revolves around the concept of single photons in the context of double slit experiments, exploring how single photons are defined, methods for generating them, and the implications for experimental setups. The scope includes theoretical and experimental aspects of quantum mechanics.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant questions how a single photon is defined and what methods exist to fire them controllably.
- Another participant asserts that a "tick" in a detector, such as a photomultiplier tube, indicates the detection of a single photon.
- There is a request for clarification on whether there is a known method to fire a single photon from a source.
- A participant confirms that single photons can indeed be fired and that this is how double slit experiments are conducted.
- One suggested method for achieving single photon emission involves using a dim light source with neutral density filters to reduce the photon rate.
- A later reply mentions that there are established schemes for producing single photons on demand, providing a link to a resource for further information.
Areas of Agreement / Disagreement
Participants express differing views on the methods for generating single photons, with some asserting that it is possible while others seek clarification on the mechanisms involved. The discussion remains unresolved regarding the specifics of photon generation techniques.
Contextual Notes
Limitations include potential assumptions about the definitions of photons and the effectiveness of various methods for generating single photons, which are not fully explored in the discussion.
