alen,

It is very true that the "wave function" or amplitude function is not physically present in spacetime although the probabiliy determined from it is physically significant in spacetime. The problem with dismissig the wave function as unreal is that there is no hole in the math/physics nexus that is quantum physics.

Scientists use the wave functions to set up single particle experiments that exhibit quantum weirdness. And the experiments work as advertised. Others perform calculations with "qubits", and the calculations work.

Dirac found that the wave function could be married to relativity, and the result was not only accurate, but beautiful. Others found QED to be just as relativistic and even more accurate, although its beauty strikes us more today than it did its founders.

What the amplitude function is when it's at home, whether a section in a bundle over spacetime, or a representation of our state of knowledge, or whatever, it can't be denied that it works.

Regards,
Dick
