Wave Function Collapse using faulty recording devices.

Click For Summary
SUMMARY

The discussion focuses on the effectiveness of measuring devices in the context of the Double Slit Experiment and the Wave Function Collapse. It establishes that if a measuring device has a less than 100% detection rate, such as a 50% chance of being operational, the collapse does not occur when the device is off. Additionally, it highlights that undetected particles can still create a double-slit interference pattern, while detected particles form separate single-slit patterns, resulting in a combined total pattern.

PREREQUISITES
  • Understanding of the Double Slit Experiment
  • Knowledge of Wave Function Collapse
  • Familiarity with quantum measurement theory
  • Basic concepts of particle detection and interference patterns
NEXT STEPS
  • Research the implications of measurement in quantum mechanics
  • Explore the role of observer effect in quantum physics
  • Learn about quantum superposition and its relation to interference patterns
  • Investigate different types of measuring devices used in quantum experiments
USEFUL FOR

Physicists, quantum mechanics students, and anyone interested in the principles of wave-particle duality and measurement in quantum theory.

TL;DR
Effectiveness of faulty observational devices during the Double Slit Experiment and the Wave Function Collapse.
Hey there!
I have two questions regarding the Double Slit Experiment and the Wave Function Collapse.

How effective does a measuring device have to be to cause a collapse? As in, say that every second the device has a 50% chance to turn off or on for one second, does the collapse still occur when the device has shutoff?
Similarly, suppose an observer has been awake for a few days and perhaps even on a drug trip that is rendering them in and out of consciousness, is there a threshold in which the observation does not occur?

Thank you for your time!
<3 Phillip.

It's not just faulty measuring devices, a device to detect a particle may simply not be 100% effective. E.g. if only 50% of particles were detected (at one slit or the other) and 50% went undetected, then these 50% undetected particles, between them, would form a double-slit interference pattern; and, the detected particles would form two separate single-slit patterns (assuming the detection did not significantly influence this). The total pattern, therefore, would be this combination of patterns.

Silly me, it didn't occur to me that I have to rotate by 90 degrees. :heart:
