Mach zehnder : a test for superposition ?

[jk22]

We consider a one photon experiment. If the photon really follow both path at the first beam splitter then only one detector will click, if on the other hand the photon would have to choose one path (classical particle) then both detector could click ?

No, as there is only one photon which can make only one detector click.

Right it is badly expressed. I should have said the other detector could click. In this second view only one detector clicks but it could be one or the other if we repeat the experiment.

Yes, that would be the case.
