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:

    In this distribution of functions, the scholar is the delegated intellect. In the right state, he is, Man Thinking. In the degenerate state, when the victim of society, he tends to become a mere thinker, or, still worse, the parrot of other men’s thinking.
    Ralph Waldo Emerson (1803–1882)
