What does Dirac mean by "the suffixes would not balance"?
.
Even with that fixed, as has already been said, your equation makes no sense because the indexes don't match. Here's a suggestion: take...

Feynman rules for Entangled photons

@Demystifier described how this works in configuration space in post #4. See further comments below. You can do it either way. Doing it...

Is quantum interference an instantaneous consequence of superposition ?
.
Thread closed for moderation. @Husserliana97 if you can get a valid reference, PM it to me and I will take a look and reopen the thread...

This is not a valid reference. If your physicist can't point you to a valid reference (textbook or peer-reviewed paper) that expounds...

Conservation of energy and wave function collapse
.
If you take this approach, the question becomes interpretation dependent. And discussion of that aspect belongs in the interpretations...

Doing this requires considering the system you are measuring as an open system--it exchanges energy with other systems, during...

That's not what @Demystifier said. What he said is that you need to first decide what you are computing the path integral for. Are you...

What are a and b? You're assuming it's obvious. It's not. Once you answer what a and b actually are, you will know the answer to the...

Amplitude for what? In order to even do a path integral, you need to define the endpoints.

New hypothesis of continuous wave function collapse

As a note, this is not a good description of what standard QM says, and the fact that this kind of description appears in the referenced...

Btw, this claim is actually interpretation dependent; it assumes that the wave functions before and after the measurement describe the...
