= Wigner–Weyl transform
{wiki=Wigner–Weyl_transform}
The Wigner–Weyl transform is a mathematical formalism used in quantum mechanics and quantum optics to connect quantum mechanics and classical mechanics. It provides a way to represent quantum states as functions on phase space, which is a mathematical space that combines both position and momentum variables. \#\#\# Key Features: 1. **Phase Space Representation**: The Wigner–Weyl transform maps quantum operators represented in Hilbert space into phase space distributions.
