SUMMARY

The forum discussion centers on the superposition angle range in the context of the double-slit experiment. It establishes that matrix-based equations indicate a finite number of possible superpositions and emphasizes the importance of the distance between slits in reproducing the experiment. The conversation also addresses the uncertainty in the direction of the beam and its impact on the detection patterns, concluding that while there is a non-zero chance for photons to be detected in various directions, focused beams significantly limit detection outside a narrow strip.

PREREQUISITES
  • Understanding of quantum mechanics principles, specifically superposition.
  • Familiarity with the double-slit experiment and its setup.
  • Knowledge of probability distributions in quantum physics.
  • Basic concepts of photon behavior and detection mechanisms.
NEXT STEPS
  • Research the mathematical framework of superposition in quantum mechanics.
  • Explore the implications of slit distance on interference patterns in the double-slit experiment.
  • Study the role of uncertainty in quantum measurements and its effects on photon detection.
  • Investigate advanced topics in quantum optics related to focused beams and detection probabilities.
USEFUL FOR

Physicists, quantum mechanics students, and researchers interested in the principles of superposition and experimental setups in quantum physics.

Question on superpositions
With superpositions, the matrix based equations imply that there is a finite number of possible superpositions. Descriptions of how to reproduce the 2-slit experiment prescribe a maximum distance the slits can be apart and still reproduce the experiment.

is there a way to determine the minimum and maximum angles a superposition could have from the emitter?

This question does not make much sense to me. For a double slit experiment, you need the slits to be within the uncertainty in the direction of the beam. But, also, if the slits are far apart and you have a very large uncertainty in the direction of the beam, then you will effectively get two separate single slit patterns, some distance apart.

What defines the boundaries of the uncertainty?

There is no definite boundary, but the probability distribution will drop off very quickly for a tightly focused beam.

So there is a non-zero chance that a single photon could impact a detector 180 degrees behind the emitter?

That's not really relevant. If the emitter is a simple source, then photons will be detected in all directions. If the emitter produces a focused beam, then the probability of being detected outside a narrow strip on the first screen would be vanishingly small.
