Postulates of Quantum Mechanics
The rst important idea in mechanics is the state of a system, and if one knows
the state, then in principle one can predict the state of the system any future
time. In the classical scheme, pos

Introduction
In this note we develop an elegant and powerful formulation of quantum mechanics, the density matrix formalism. This formalism provides a structure
in which we can addre
