description Overview

Wigner function

The Wigner function is a mathematical tool used in quantum mechanics. It provides an alternative approach to describing quantum states by representing their amplitude across phase space – a combination of position and momentum. This allows physicists to visualize and analyze quantum behavior, particularly when studying transitions between classical and quantum descriptions. It’s most useful for re...

density matrix

The density matrix is a mathematical tool used in quantum mechanics to represent the state of a quantum system. It accounts for both known and unknown components within that state, including mixed states resulting from interactions or entanglement. This formalism provides a way to describe open systems – those interacting with their environment – where a definite pure state cannot be defined. Dens...
