- There is nothing wrong with the description you provided for a single
- photon. The reason it does not apply to the singlet state case is that
- all the changes you described can be modeled by the Schrodinger equation.
- They do not represent a change in state of the photon but only describe
- how the wave function evolves in time and space. Because the
- evolution of the wave function as governed by the Schrodinger
- equation is local you cannot use it to model what happens in the
- singlet state case. If you could the relativistic Schrodinger equation
- would not be Lorentz invariant. You would have distant changes in
- polarizer angles instantaneously changing the structure of the physically
- distant wave function.
