Is there an interference pattern within a non-interference pattern?

Click For Summary
The discussion explores whether an interference pattern exists within non-interference patterns in two scenarios involving single photons. In Scenario 1, a single slit produces a column of dots without any hidden interference pattern. Scenario 2, with a double slit and measurement of the photon’s path, results in two distinct columns, leading to debate over the presence of hidden interference patterns within each column. The conclusion varies among participants, indicating that interpretations of quantum mechanics influence the understanding of these phenomena. Ultimately, the question remains open to interpretation regarding the nature of photon behavior in these contexts.

Consider two scenarios:

Scenario 1:

Single slit, single photons sent one by one.

We would have a blob or column of dots. However inside this column is there an interference pattern hidden?

Scenario 2:

Double slit, single photons sent one by one, however we have instrumentation in place to find out which slit the photon went through.

In this case there would be two columns of dots. However inside (each of) these two columns is there an interference pattern hidden?

In summary:

Could a single photon via a single slit still be interfering with "itself"?

No.

Some say yes - some say no. Depends on interpretation.
