The Foundations of Quantum Mechanics
The postulates of quantum mechanics are mathematical prescriptions for using the theory to predict the results of experiments. These postulates can be presented in terms of the state vector or by using the density operator. We discuss both topics and cover material related to the representation of composite quantum states and the Heisenberg picture. We also introduce a useful tool for two-level systems called the Bloch vector.
