Abstract
We show that for quantum tomography there exist two mutually conjugating intermediate coordinate-momentum entangled states |η1,η2ãλ,ν and |Ï1,Ï2ãÏ,Ï. The Radon transforms of the Wigner operators are just the pure-state density matrices |η1,η2ãλ,νãλ,νη1,η2| and |Ï1,Ï2ãÏ,ÏãÏ,ÏÏ1,Ï2|, respectively. As a result, the tomogram of quantum states is the module-square of their wave function in these representations. A new convenient formalism of quantum tomogram is thus established.
