Tomography of a three-photon state. a Diagram of the three-photon GHZ state. b Simulated correlations of the GHZ state after propagation through the measured transfer function of the device in Fig. 2a. Gaussian error with standard deviation of 5% the maximum correlation element’s value is added to each element. c The real part of the GHZ state’s density matrix. d Real part of the density matrix that was recovered using the simulated correlations from (b)
