Wave function is always in abstract space in any quantum interpretation be it Copenhagen or Bohmian or Many Worlds because wave function is in many dimensional abstract Hilbert Space. Correct?(adsbygoogle = window.adsbygoogle || []).push({});

Since the counterpart of Hilbert space in QM is Fock Space in QFT. Then the fields in QFT live in abstract space too. Correct?

This means electron field in QFT live in higher abstract space. But in QED, electromagnetic field live in Fock space too in abstract space, but how come we can detect electromagnetic field? Or is the answer we can't really detect electromagnetic field directly but just the photons when they couple to the electrons in an antenna and vibrate them up and down?

If the answer is we can detect electromagnetic field directly. But electromagnetic field is supposed to live in Fock space in abstract space. So how can we detect or touch things in Fock space when it is supposed to be located in higher abstract space?

Hope someone can clear this up as it sometimes still confused me. Thanks.
