Wigner Distribution

The Wigner distribution is either of two things:

  • Wigner semicircle distribution - A probability function used in mathematics (Eugene Wigner)
  • Wigner quasi-probability distribution - A distribution in phase space encoding, in a convenient representation, properties of quantum-mechanical wave-functions. Strictly speaking, it is the Wigner map of the density matrix in the Weyl correspondence. In signal analysis, it is known as the Wigner-Ville distribution. It is useful in quantum statistical mechanics, quantum chemistry, optics, quantum computing etc. (Eugene Wigner, Hermann Weyl, J. Ville)

Famous quotes containing the word distribution:

    There is the illusion of time, which is very deep; who has disposed of it? Mor come to the conviction that what seems the succession of thought is only the distribution of wholes into causal series.
    Ralph Waldo Emerson (1803–1882)
