No-go theorems for photon state transformations in quantum linear optics

open access: yesResults in Physics, 2023
We give a necessary condition for photon state transformations in linear optical setups preserving the total number of photons. From an analysis of the algebra describing the quantum evolution, we find a conserved quantity that appears in all allowed ...
