Double Slit detectors question

Click For Summary
SUMMARY

The forum discussion centers on the implications of detectors in the double slit experiment and the concept of "observation" in quantum mechanics. Participants emphasize that detectors do interfere with the experiment, leading to different results when present versus absent. The discussion highlights that quantum objects exhibit wave-particle duality, but this concept is outdated; instead, they behave as excitations of quantum fields. The challenge in providing a mathematical explanation for "observation" stems from its vagueness and the complexity of translating quantum laws into classical measurement results.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with quantum decoherence
  • Knowledge of wave-particle duality
  • Basic concepts of quantum field theory
NEXT STEPS
  • Research quantum decoherence and its mathematical framework
  • Explore the implications of the quantum eraser experiments
  • Study the differences between classical and quantum measurements
  • Investigate the role of information in quantum mechanics
USEFUL FOR

Physicists, students of quantum mechanics, and anyone interested in the philosophical implications of observation in quantum experiments.

When does this correlation between Bob and Alice's data manifest itself.
1. After Alice's recordings but before Bob's recordings.
2. After Alice's recordings and after Bob's Recordings
3. After Alice and Bobs recordings have been compared.

And further if the answer is 3 above, does it imply that the correlation could not exist ,between the time interval of event 2 and event 3?
Or even between event 1 and event 2 for that matter?

Orthodox QM is relatively silent on the specifics of when such correlations (and entanglement itself) begin and end. Different interpretations can yield different answers, and there is no specific test available to clarify. All you can do is predict the ultimate outcomes, and the rest is up to you. :smile:
