We present a method of generation of the Greenberger–Horne–Zeilinger state involving type II and type I parametric downconversion, and triggering photodetectors. The state generated by the proposed experimental set‐up can be reconstructed through multi‐mode quantum homodyne tomography. The feasibility of the measurement is studied on the basis of Monte‐Carlo simulations.
