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

A density matrix represents the state of a quantum system in a form that can describe both pure states and mixed states. A pure state can be represented by a single state vector, while a mixed state involves a statistical mixture. The density matrix allows both cases to be handled within one mathematical framework and supplies the information needed to calculate measurement probabilities and expec...
