Large photon number semiclassical asymptotics of the HOM interferometer with partially indistinguishable photons
Miguel Villalobos, Alejandra Valencia, Alonso Botero · 2024
The classical correspondence of the HOM interferometer with n → ∞ partially indistinguishable photons is shown to arise from a concentration phenomenon of the quantum state in a Hilbert-space sector that can be associated with a well-defined macroscopic fraction of effectively indisistinguishable photons.
