description Overview

interaction picture

The interaction picture in quantum mechanics reformulates time evolution by shifting the time dependence from operators to states, isolating how interactions alter system dynamics relative to free propagation.

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.
