Quantum optics

the volume of negative values in a state's Wigner function, used as a measure of nonclassicality.

In quantum optics, Wigner function negativity refers to the volume of negative values in a state's Wigner function, used as a measure of nonclassicality. This meaning comes from Kenfack (2004) in Journal of Optics B: Quantum and Semiclassical Optics.[1]
