B Wave Function Collapse using faulty recording devices.

Click For Summary
The discussion centers on the effectiveness of measuring devices in the context of the Double Slit Experiment and Wave Function Collapse. It highlights that a measuring device does not need to be 100% effective to influence the outcome; even a 50% detection rate can lead to a combination of interference patterns. If a device is turned off, the collapse does not occur, allowing undetected particles to create an interference pattern. Additionally, the state of the observer, such as being in and out of consciousness, raises questions about the threshold for observation and its impact on the collapse. Overall, the effectiveness of measurement and observation plays a crucial role in quantum mechanics.

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!

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.

Oh wow, fascinating! <3

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