In the book 'Quantum Physics', Alastair Rae uses polarized photons and photon detectors to describe many effects observed in quantum physics. In his typical setup, photons are passed through a polarizer and exit it through two different channels depending on the polarization [itex]\phi[/itex] or [itex]\phi+90^\circ[/itex] they then have. Behind each channel, there is a photon detector to tell through which of the two channels "the" photon exited.
Now my question: Where does the wave function representing the photon collapse?
Now my question: Where does the wave function representing the photon collapse?
- Does it happen in the polarizer, when the photon's polarization is decided to be either [itex]\phi[/itex] or [itex]\phi+90^\circ[/itex], or
- does the wave function collapse only later in the detector?
