We demonstrate that the Wigner function of the Einstein-Podolsky-Rosen state,though positive definite, provides a direct evidence of the nonlocal characterof this state. The proof is based on an observation that the Wigner functiondescribes correlations in the joint measurement of the phase space displacedparity operator.Comment: 3 pages, REVTe
