Has the double-slit experiment been conducted with multiple observers?

Click For Summary
SUMMARY

The double-slit experiment demonstrates that the act of observation alters the behavior of photons or electrons, resulting in the disappearance of the interference pattern. This phenomenon occurs regardless of whether one or multiple observers are present. The discussion confirms that the interference pattern is destroyed when any measurement is made, leading to particle-like behavior. For further clarification, a detailed description of the double-slit experiment can be found at the provided link.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with the double-slit experiment
  • Knowledge of photon and electron behavior
  • Basic concepts of measurement in quantum physics
NEXT STEPS
  • Research the implications of observation in quantum mechanics
  • Explore variations of the double-slit experiment with multiple observers
  • Investigate the role of measurement in quantum state collapse
  • Read about the philosophical interpretations of quantum mechanics
USEFUL FOR

Physicists, students of quantum mechanics, and anyone interested in the foundational principles of observation and measurement in quantum theory.

Hello All,

I hope that this question has not yet been asked.
I'm interested if the double-slit experiment has been conducted with more than one observer.
I mean one (or more) "light-measuring devices" that have been set on every slit for the sake of verifying if the results come out differently.
It would be very helpful if you could provide any links or literature where I can clarify this issue.

Thanks a lot

If you observe which slit it goes through the interference pattern disappears - that's the case whether you observe just one slit or both.

I don't know if the experiment has been done, but what will happen is very well known.

Thanks
Bill
 
The thing to remember about the double-slit experiment is that the act of observing the photons or electrons involved requires that you interact with them - which destroys any interference patter you might have had, and leads to particle-like behavior.

I have a good description of the double-slit experiment here: http://keirionparadigms.com/HThesis/HThesisDoubleSlit.html
