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