description Overview

density matrix

A density matrix describes the state of a quantum system, even when that state is unknown or entangled, by representing probabilities across possible pure states and their mixtures.

Wigner function

The Wigner function represents a quasi-probability distribution in phase space, offering a way to analyze quantum states by mapping them onto a classical-like representation despite not always being positive.
