Eliminating the coincidence counter

[Fiziqs]

In DCQE, if you leave out the coincidence counter, does it effect the results at D0? Or is it impossible to know?

What I want to know is...do you collapse the wave when you measure the particle...or does that information need to be accessible to a human observer.

Or even simpler...in the double slit experiment, if you measure which slit the particle went through, and then destroy any information about the result, without ever knowing what it was, does the interference pattern disappear?

Thanks

If which slit information was written by a robot arm onto paper and then the paper burnt, so no observer could read it ever again? hmmmm...

for your question. Eliminating the coincidence counter in DCQE may or may not affect the results at D0, depending on the specific experiment being conducted. The coincidence counter is used to detect and record simultaneous events, and its absence could potentially lead to missed data or inaccurate measurements. However, it is impossible to know for sure without conducting the experiment and analyzing the results.

As for the concept of wave collapse and the role of human observation in quantum mechanics, it is a highly debated and complex topic. According to the Copenhagen interpretation, the act of measurement by a human observer is what causes the wave function to collapse and determines the state of the particle. However, there are other interpretations that propose different explanations for wave collapse and the role of observation.

In regards to the double slit experiment, if you measure which slit the particle went through and then destroy the information without ever knowing the result, it is likely that the interference pattern would still disappear. This is because the act of measurement itself disrupts the quantum system and alters the outcome. However, the exact outcome would depend on the specific experimental setup and conditions.
