“…Later, Smithey, Beck and Raymer also pointed out that once the distribution P θ (q θ ) are obtained, one can use the inverse Radon transform familiar in tomographic imaging to obtain the Wigner distribution and density matrix [4]. In the last decades, the theoretical development in quantum tomography has progressed in the direction of determining more physical relevant parameters of the density from tomographic data [3,[5][6][7][8][9].…”

Based on the newly constructed tripartite entangled state representation and the three-mode Wigner operator whose marginal distributions give the probability of finding the particles in an entangled way, we generalize the tomographic theory to three-dimensional phase space. The entangled Radon transform parameters for the entangled Wigner operator are suitably chosen and the correct quadrature operators are obtained. The eigenstate of the new quadratures is also derived.
