Six quantum states with a mean photon number of 3 detected by on/off detector arrays. (a) Calculated relative entropy for the six states as a function of detector number. (b) and (c) Calculated relative entropy of each state based on 16 on/off detectors with finite quantum efficiency and dark counts. (d) Calculated relative entropy of the Fock state based on imperfect on/off detector arrays for ν = 5 × 10⁻⁶ and η = 0.9.
