Quantum Mechanics Postulates

This lecture covers the postulates of quantum mechanics, starting with the description of a physical system as a vector in a Hilbert space, followed by the evolution of the system governed by a self-adjoint operator. It then explains the measurement process using operators and the modification of the system's state after measurement. The concept of composite systems is introduced, where the total system state is a tensor product of individual states. Examples with qubits are provided to illustrate the postulates.
