Wave functions for photons are a major problem. For example the mere fact that detection destroys a photon makes the definition of position eigenstates problematic to impossible. While there are some approaches, there is no generally accepted mainstream way to formulate wave functions for photons.

But in most standard situations a wave function is defined in terms of amplitudes of possible experimental outcomes. So shouldn't this be true for multi-photon states as well?
Suppose we have a bi-photon |2V,0H> i.e. both photons are vertically polarized, and none is polarized horizontally. Can Quantum Optics predict the amplitude of all 4 possible pairs of outcomes RR, LL, RL, LR if one measures both photons in the same (e.g. circular) basis?
