    "abstract": "We demonstrate that the Wigner function of the Einstein-Podolsky-Rosen state,\nthough positive definite, provides a direct evidence of the nonlocal character\nof this state. The proof is based on an observation that the Wigner function\ndescribes correlations in the joint measurement of the phase space displaced\nparity operator.",
