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:
“The man who pretends that the distribution of income in this country reflects the distribution of ability or character is an ignoramus. The man who says that it could by any possible political device be made to do so is an unpractical visionary. But the man who says that it ought to do so is something worse than an ignoramous and more disastrous than a visionary: he is, in the profoundest Scriptural sense of the word, a fool.”
—George Bernard Shaw (1856–1950)
